Amorphous magnetic materials, grain boundaries, and it could avoid the head tip off, the friction of the head and the tape magnetic noise than the average head, excellent sound effects and long service life. Magnetic recording is the use of magnetic principle input (write), recording, storage and output (read) sounds, images, numbers and other information technology. Magnetic recording media of hard magnetic materials, the main requirements for magnetic recording media materials: an appropriate high coercivity Hc and resistant to environmental magnetic interference; high saturated magnetic polarization the strength μ0Ms, in order to obtain high output; remanence ratio Mr / Ms., can reduce the self-demagnetization effect, to improve the record efficiency; steep hysteresis loop, in order to reduce the output pulse width, improve credited to the information resolution; and requires a high stability. Can an emitter of laser pointer control several receivers of wireless presenter laser pointers?
Now widely used tape, disk, magnetic cards, a magnetic recording medium. Has been applied to a monk in the development of magnetic recording medium is divided into ferrite and metal into two categories, or divided into two major categories of the magnetic powder and a continuous magnetic film, including the following types of magnetic materials: of γ-Fe2O3 and Co-doped Co γ -Fe2O3 magnetic powder, is currently the most widely used magnetic recording materials. CrO2 magnetic particle, its magnetic properties such as coercivity, saturation magnetization, remanence ratio and the magnetic anisotropy constant is higher, but the Curie point (120 ° C), the preparation process and the need for high temperature, high pressure, catalyst, etc. conditions hinder its application. Metal magnetic film in the general magnetic recording mainly Fe magnetic film and Fe-CoDU two kinds of magnetic film, the former high saturation magnetization than the latter, but the coercivity is lower than the latter. laser pointer can run smoothly under Windows 98/2000/ME/XP and so on.
In these applications generally want to apply the three main types of magnetic materials. The first type is the rotating magnetic materials, applied to a variety of positive and negative direction of propagation characteristics of nonreciprocal microwave devices, such as the impedance of the positive and negative direction of propagation is very different from the rotating magnetic isolators and rotation of the ring line, etc., used gyromagnetic materials gyromagnetic ferrite material with high spin magnetic resistivity, such as garnet-yttrium ferrite (Y3Fe5O12) system, magnetoplumbite type barium ferrite (of BaFe12O19) system, and so on.

No drive is needed to be installed for laser pointer

So why do we also see non-luminous objects? Because the light emission of the light shines on them, non-luminous objects by light, the diffuse reflection of light in all directions into the goal of our eyes so we can also see non-luminous objects. Of laser light and ordinary light is significantly different. Such as ordinary incandescent light source is the current heated tungsten atom to the excited state, in the excited states of atomic spontaneous emission and light-emitting. This ordinary light scattering and diffuse, and can not control the formation of the focused beam, it can not be used in laser printers. The laser beam laser printer must have the following characteristics. No drive is needed to be installed for laser pointer .
A certain kind of light conductor, only the light of a regional spectrum of light perception high, leaving the region, possible loss of light sensitivity. Photosensitive semiconductor optical wavelength range applicable, will light the formation of an absorption peak. Photoconductivity peak within the best results. It with light illumination. The higher illumination, the carrier generated by the more, the optical conductivity is higher. However, the characteristics of each photoconductor different under the same conditions, to achieve the illumination of the same optical conductivity indicators are different. Drum commonly used photoconductive material cadmium sulfide (CdS), selenium - arsenic (Se-As). Organic photoconductive material (the opc) and several. The warranty of laser pointer contains the replacement requirement of laser pointer .   Production of drum used in the photoconductive material, should have the following characteristics: good wear resistance. Photoconductor surface to have a certain hardness to withstand the mechanical wear in the developing transfer and cleaning process. If the drum (photoconductor) is worn or scratched, will lead to the decline in print quality or destruction of the drum, badly worn, only scrapped. Scrapped due to wear and tear, scratches and drum in the actual work. Now a new type of long-life ceramic drum (a-Si) has been applied, you can print more than 300,000. Good temperature stability. The performance of the photoconductor easily affected by temperature, so in the performance of laser printers, with particular emphasis on the environment have the right temperature and humidity, otherwise it will affect print quality. The strike between dots of laser pointer will be formed.
Photoconductivity. Photoconductivity is an important indicator of the drum, it directly affects the print quality is good or bad. The drum work continuously in the charge and discharge cycle, the requirements of the charging potential rising fast, the surface saturation potential is higher than the application potential; Otherwise, the initial potential do not increase, will also affect print quality. Charging drum after dark decay should be small, otherwise maintain not to the surface potential, can not form the necessary potential difference between the latent image.

Laser material for solid-state laser work of N d: YAG rod, the laser wavelength of 1.06μm. Since this type of laser for laser conversion efficiency is low, by both volume and thermal conductivity of YAG rod limit, the laser output average power is not high. However, N d: YAG laser can be compressed by switching the laser output pulse width, pulse work in order to obtain high peak power (108W), for applications requiring high peak power laser processing applications; N d: YAG laser Another advantage is transmitted through the optical fiber, optical transmission to avoid the complexity of the design.
For example, laser drilling of jewels can be used as 0.6943μm the ruby laser wavelength, the wavelength of 1.06μm Nd: YAG laser and a wavelength of 10. 6μm the CO2 laser; of glass, quartz, ceramics and other materials, laser drilling , then use the CO2 laser wavelength of 10.6μm more favorable for processing. Laser cutting is the use of the laser beam is focused to form a high power density of the spot light parts, materials absorb light energy, the temperature rises rapidly, the material rapidly heated to melting or vaporization temperature, and then blowing of the gas jet, in order to separate materials. In this process, the laser light hits the surface, the part of the light absorbed by the workpiece, and the other part of the light reflected by the workpiece. Absorb some heat into the workpiece surface temperature increased rapidly, the material melting or vaporization, while a black hole effect, and the material light absorption rate, rapid heating and melting or vaporization zone material. The school party needs more green laser pointer for entertainment. red, the surface is very uneven, there is a strong tendency to spatter, and weld processing conditions on the back can not see the beginning signs. Too much laser energy is concentrated in the wire, so that the solder to become overheated. While at the same side of the workpiece has not been heated enough so that the solder does not flow easily to the gap in the workpiece. In addition to these factors, laser brazing process also affected by welding lens group and the wire feed speed to speed. Amount of solder must be required by the weld area and weld parts to be processed to determine the length, solder supply unit time by the wire feed speed and welding wire cross-sectional area to determine.

Mainly by high-speed comparator and its subsidiary circuit. Input Gaussian pulse signal is divided into two: all the way through the delay circuit delay added to the high-speed comparator inverting input and the other path attenuation circuit added to high-speed comparator inverting input of the comparator transitions occur in the two input moment of the relative size of the end of the signal change, the role of the threshold amplitude greater than the specified threshold signal to produce a corresponding output signal at the output, which prevents noise and false triggering, reducing the false alarm rate of the system. Delayed attenuation circuit design: the signal after a certain device and transmission line there is always a slight time delay, the delay of high-speed analog signal is generally achieved through a transmission line. Lead the healthy consumption of laser pointer industry.
Design considerations to achieve the delay of the signal RC delay circuit consisting of capacitance and resistance. Specific circuit is as follows: the structure and principle of laser camera. The basic structure. Laser printing systems: including laser transmitters, regulators, divergent lens, polygonal lens, focusing lens, high-precision motors and rollers.

Its function enough to remove the film from the sheet feeding box after transmission device to send a laser scanning position, when the film exposure is completed and then transfer it to the closing piece box or directly to the washing machine lose Piankou, to complete the film conveying task. Information transmission and storage systems.This advantage of laser pointer can attract more and more customer
Abstract: This paper KODAK 8100 camera a few failure analysis, check the possible ways to solve the fault and prevent failures from happening again, for the peer reference. KODAK 8100 laser camera, a Kodak Company introduced a few years ago, print and slice one dry-type semiconductor laser camera design, low failure rate, the more ownership. In this paper, several fault common to talk about their own maintenance experience, or to give peer reference. Failure: Boot error in the heating drum preheat the P551 (not warm-up imaging device, the imager can not be printed). Analysis of maintenance: failure prompted the instrument self-test after the preheating process.Dry laser imaging using a laser beam scanning of film exposure to generate the latent image, laser imager, laser point in the X and Y directions form a clean, sharp edges, thus providing higher resolution, print resolution from 325 dpi to 650dpi, 14 16384 gray.

In this process, the use of photosensitive detectors from a fixed beam diversion mirrors the continuous collection of signal feedback to the laser generator, so that the source laser beam remains stable. Control with a rotating beam diversion mirrors the beam sent to its light-sensitive film in this way is called the X-axis fast scanning. The drum of the camera cabinet is a fixed-speed transmission film, in this way is called the Y-axis slow scan. In this way, the camera 6o0 line / second image data transmission speed and accurate copy of all the images. Film cassette from the storage for the film (which can accommodate up to 100 laser sheet) automatically provides the guide shaft transmission mounted on a dedicated print drum, roller then go to the print position. Whether the power of laser pointer can meet the use requirements of the customer.
To go through a series of processing an amendment to adjust the image size, size, and layout. The laser head based on the strength of the different layout after the image signal output of the laser, thus completing the film scanning process. The processing capability of the laser camera determines the camera's image quality, adaptability and range of applications. Grasping piece institution control system: responsible will need to scan film grabbed anyone to the laser scanning area. The laser print control system: the wet laser printer control systems Part 2 by laser scanning and film transfer. Layout to complete the image signal by the control circuit into the laser scanning optical signals required. The laser beam is calibrated by a line scan (from left to right) to form a latent image of the image signal on the film. The low power of laser pointer is enough to meet the customer’s requirements and needs.
Dry laser camera with DICOM3.0 to interface to connect multiple images through the PACS network equipment, and the sharing of resources. When multiple devices at the same time came the image signal can be pre-set their priorities, which device the film takes precedence over print. The camera can also be printed image to be stored, if necessary, can be directly selected in the camera out of print without the need to re-take pictures. Based on dry laser cameras for all to see these benefits, but also with the development of computer technology, its spatial resolution and gray scale grade higher and higher, faster and faster print speed, imaging results fully comparable with the wet laser imager, Therefore, more and more hospitals are recognized. The different powers of laser pointer are needed.

The magnitude of increase in fiber optic transmission capacity

laser pointer has the high cost performance.
CATV optical networks, in order to ensure the uninterrupted operation of cable systems should be equipped with backup optical transmitter, when the working of the optical transmitter failure, the use of optical switches within a very short time the backup optical transmitter access system, to ensure their normal work. According to their works, the optical switch can be divided into mechanical and non-mechanical two categories. Mechanical optical switches rely on optical fiber or optical components to move the optical path to change the light switch on the market today is generally a mechanical advantage of a low insertion loss, generally less than 1.5dB; high isolation, typically greater than 45dB, free from polarization and wavelength. Non-mechanical optical switches rely on electro-optic effect, magneto-optical effects, sound and light effects, as well as thermo-optic effect to change the waveguide refractive index, so that the optical path to change. The customer can focus the energy of laser pointer .
This is also a new technology, the advantages of these switches are: the switching time is short, small size, ease of optical integrated optoelectronic integrated; the inadequacies of the insertion loss, isolation, low. Within an optical fiber for simultaneous transmission of several different wavelengths of light signal communication received WDM do, using WDM technology, as long as a small amount of co-wave transmitter and the receiver, sub-wave devices, you can The magnitude of increase in fiber optic transmission capacity and increase economic efficiency. Fiber optic cable has been laid, the use of WDM technology, multiplexing, and play a role in lower costs and expand capacity. WDM in the optical path to play the role of co-wave and sub-waves. The user can adjust the emitted laser beam light of laser pointer .The customer should protect themselves especially their eyes with goggle of laser pointer
It brings together the different wavelengths of light signals (wave) to an optical fiber transmission to the receiving end, again by the multiplexed optical signal to the optical fiber transmission separation out. Can be divided into branches mirror type, according to the spectrophotometric principle, WDM interference model and the diffraction grating are three products on the market most of the diffraction grating. The main indicators of the WDM insertion loss, crosstalk loss, wavelength interval and mpx. The insertion loss of the use of WDM and optical power loss is generally about-5dB. Crosstalk loss represents the WDM separated on the wavelength.

A and reduce stomatal diameter d can be large mode area

The customized service of laser pointer can help the customer save more money.
Fiber end as the resonator mirrors, plus the required pumping source, they constitute a linear FP cavity structure of the PCF laser. PCF lasers with conventional fiber laser main difference lies in the gain medium of PCF. Used by the PCF different PCF laser devices can be divided into two categories: one is the small mode area PCF nonlinear effects of laser devices; the other is the use of large mode area (LMA) of the doped rare earth elements of PCF (especially double-clad the layer PCF) developed high power, high beam quality near-infrared PCF laser. Ordinary fiber laser to improve power often at the expense of beam quality for the price, high-power PCF lasers. The customer can put forward some specific requirements for the appearance of laser pointer .
The large mode area PCF not only can improve the coupling efficiency of fiber laser pump beam, but also effectively reduce the nonlinear effects in fiber and high pump power, high power and high beam quality laser output. Double-clad PCF in photonic crystal fiber with cladding pumping technology, provided the conditions for the further development of the high beam quality, high power fiber lasers; fill the air by increasing the cladding layer than can increase the outsourcing The rare earth doped double-clad photonic crystal fiber cladding relative refractive index difference, thereby increasing the numerical aperture of the fiber cladding; by increasing the stomatal spacing A and reduce stomatal diameter d can be large mode area. The manufacturer can produce laser pointer for the customer.Where: h-Planck constant;-speed of light; the Eg-band gap semiconductor. Due to spontaneous recombination of electrons and holes and luminous phenomenon known as spontaneous emission. When the spontaneous emission of photons by the semiconductor, has launched an electronic - hole near create an incentive for both composite and generate new photons, such photons to induce excited carrier recombination and issued a new photon The phenomenon is known as stimulated emission. If the injection current is large enough, will be the formation of the thermal equilibrium carrier distribution, ie, the population inversion. When the carrier within the active layer in a large number of reverse case, a small amount of spontaneous emission of photons due to the reciprocating reflection of both ends of the cavity surface is induced by radiation, causing the selected frequency resonant positive feedback. The customer can require some special customized service of the focusable performance of laser pointer .
Or gain of a particular frequency. Have good lines of coherent light - laser when the gain is greater than the absorption loss can be issued from the PN junction, which is the simple principle of the laser diode. With the development of technologies and processes, the actual use of the semiconductor laser diode has a complex multi-layer structure.

laser pointer will be tested in the testing center of laser pointer

Production Supervision of laser pointer
Graphic projection is not easy to flicker. In actual use, not to set the scan rate the higher the better. It also required the user to output the graphics appropriate adjustments. Scanning step. Users to draw graphics using laser projection software can find a drawing by a number of discrete trajectory in the graph "nodes" consisting of. The so-called "step" is the distance between these points. As a graph, the smaller the output steps more graphics "realistic", but the composition graph "nodes," the number will increase. If the graphics are too many points, it will cause the flashing graphics output. The new production line of laser pointer will greatly increase the output of laser pointer .
Therefore, the setting step to combine the output graphics of the "realistic" level, and the graphics are flashing and other factors considered. Another step of setting, with the scan rate. In general, the faster scan rate, the smaller the step size should be set? Laser switching point is often set in a continuous line of the two endpoints (see below). The reason for setting the switching point is that in a continuous line between the laser output state to change, may be closed to start from, it may be from start to close. These state changes are usually laser is instantaneous, and electromagnetic scanner because it is driven by mechanical scanning, so there is the actual speed of the scanning process and mechanical lags inertia. If the computer is sent to the scanner end of the position signal, it changes the state to send the signal laser, you will see in the output graph, the position of the laser changes the state is not required in your position. laser pointer will be tested in the testing center of laser pointer .  
The general direction of the long side with flat-top distribution (Top-Hat), the other is up nearly Gaussian distribution, or nearly flat distribution in between. Although the excimer laser light field distribution uniformity is already higher than the general non-uniformity of excimer laser is better, but because of excimer lasers in the large volume, high voltage, high-pressure state operation, easily lead to uneven discharge gain, and if the proportion of working gas changes, changes in the output pulse energy at the same time, the intensity of the beam cross-section distribution of considerable change occurred, resulting in the output light intensity distribution fluctuated considerably, from the practical application there is a gap. The new manufacture base of laser pointer draws a lot of attention.New Manufacture Base of laser pointer
In order to improve the quality of the laser beam can be used in excimer laser beam uniformity are: prism method, reflection microscopy, two compound eyes are beam-type device, the phase grating diffraction method, optical waveguide method and so on.

It is due to the special functions of laser pointer

The front is a loop, shown in Figure 4-1. Inside the loop on the button, display, and serial communication data. Background shown in Figure 4-2, the external event manager TIMER1 interrupt interrupted, as the core of the entire feedback loop in order to interrupt the basis of completion of the AD sample, PWM duty cycle calculation to update the PWM duty cycle, eventually Output PWM. Software systems need to ensure that real-time task only feedback loop task. According to the characteristics of 2812, the ISR in can not be nested interrupt [] in an ISR operation of other interrupts can not be DSP response. It is due to the special functions of laser pointer .
In order to prevent the keys or serial interrupt ISR execution time is too long, thereby affecting the implementation of the feedback loop should not be too much code in the ISR button or serial port interrupt. Therefore, the key or serial port interrupt the ISR, only the key or the serial communication data, save in one place, and then place a corresponding global flags, and then exit the ISR. Keys and serial communication data processing in the main loop, the main loop by detecting the flag to know whether there is key or serial communication event occurs, and then to specify the location to read the corresponding data processing. Doing so can maximize interrupted feedback loop task execution. Sampling control system are delayed, how to make the minimum delay. The 1000mW blue laser beam of laser pointer can easily burn match.
According to TI's Application Note [], the design shown in Figure 43 shows the structure. This program, you can ensure that the feedback loop delay time within a switching cycle. First of all, the timer interrupt and AD sampling interrupt service handler fixed number of instructions, while the AD conversion time is determined by hardware, and thus the location of a week during the period AD sample is fixed relative to the start time of the switching cycle. Select the appropriate AD sampling filter parameters, and more conducive to tracking the average inductor current. Secondly, since the call of the digital controller is AD interrupt the ISR, the AD interrupt the beginning of the interval of the switching cycle time is very short, you can ensure that the digital controller has enough time to execution. laser pointer can lighten the cigarette and paper.It is the improvement measures of laser pointer

laser pointer also plays a significant role in exhibiting

laser pointer also plays a significant role in exhibiting.
Traction is the laser linewidth and frequency to the laser characteristics. Line width is due to the presence of spontaneous emission, and therefore can not be excluded, so called width limit. Greater output power, the more narrow linewidth. This is because the output power increase means an increase in the number of cavity photon coherent, stimulated emission accounts for more than the spontaneous emission, and therefore, narrow linewidth. Reduce losses and increase the cavity length can also narrow linewidth. For example, the semiconductor laser cavity length because only a few hundred microns and has a wide laser linewidth. If it is outside mirror with a form will enable the external cavity semiconductor laser linewidth significantly reduced.
Its life span is generally room temperature up to 10 million hours of high temperature aging test at room temperature projected life span of up to one million hours, so it is a long, high-reliability products ordered. The above describes some of the development of display technology and its principles, the future development of the area will be popular in the hot, also looking forward to a breakthrough in display technology has improved. Enable students to understand the history of the laser, the formation and development of the laser, the formation of the theoretical system. Make students understand the scientific branch of the laser and laser in the military, information technology, medical, and other applications; early 1917 - Einstein first predicted stimulated emission laser. Technically the use of multi-longitudinal-mode output of the laser beam, through a special modulation, it has been determined between each longitudinal mode of the phase relations. As spontaneous and stimulated emission of radiation compared to the contribution of extremely weak, and thus the discussion of threshold issues such as output power can be negligible; But in considering the issue width Shique must consider the impact of spontaneous emission.As the role of the dye cavity gain, phase correlation part of the light field to quickly highlight, and a random part is suppressed. Phase correlation between the beat frequency model, the formation of a narrow width of the collision mode-locked pulses. This approach has been able to get the order of 10 fs ultrashort optical pulses.Because the dye medium produces rapid gain saturation effect, so the pump pulse width compared with the received pulse width becomes very narrow. Hydrogen ion mode-locked laser with 100 ps pump pulses of light from a Rhodamine 6G dye laser to obtain the pulse width 0.6-1ps, up to 1 kW peak power pulses of light.

The color of light from the light wavelength (or frequency) decision. A certain wavelength corresponding to the certain color. Wavelength distribution of sunlight in the range of about 0.76 microns to 0.4 microns, the corresponding color from red to purple, 7 colors, so the color of sunlight alone. Single-color light emission as monochromatic light source that emits a single wavelength of light. Such as krypton lights, helium lights, neon, hydrogen lights are monochromatic light sources, only a certain color of light emission. Although monochromatic single wavelength light source, but there is still a certain distribution. If only transmit red neon, color is very good, known as the highest monochromatic wavelength range of the distribution is still 0.00001 nm, so the neon red light, if carefully identified dozens of red still contains . Thus, the optical radiation of wavelength range of the more narrow distribution, the better the color. and most of cure or recovery with the wound to improve, and only a few more some degree of visual effect, so patients must have a reasonable expectation of surgery, and risk awareness. " After the acceptance, the summary meeting of laser pointer will be held.
Some patients appear to do the side effects of excimer laser? Photophobia: after surgery three to six months, increased sensitivity to light, but many will gradually disappear after 6 months, very few cases will continue. Correction of deficiencies or over-correction: residual myopia after surgery, or more than the expected degree of correction into hyperopia, is the most common side effects, as the case may be re-stabilized laser correction degree. Glare or double vision: early surgery is more common, especially at night will have a pupil larger than the majority will gradually disappear, only a small part of it will continue. Corneal flap folds or displacement: only in LASIK, may be due to trauma, can cause irregular astigmatism affect vision, surgery may be re-paved. Epidermal healing: more common in PRK, contact lenses can be therapeutic and artificial tears to help recovery. The company will make the improvement actions of laser pointer in the summary meeting of laser pointer .
Corneal opacity: only occur after PRK, with the higher degree of personal physical fitness and a positive correlation correction, 1-3 months after the most obvious point of steroid eye drops to be controlled, then most will slowly fade. Surgery complications: corneal flap cutting is bad in most, if not completely cut or cutting is not smooth; reset as long as the corneal flap can be restored, three months after reoperation. Impurities under the skin flap or invasion: a minor who does not affect vision, severe corneal flap to be opened to remove. Infection: a result of surgery or postoperative dirty, so that the wound to bacteria infection, the probability is very low, as long as early detection, most available medications.

Currently, the anti-strategic missile research and development of laser weapons, or chemical lasers, excimer lasers, free electron lasers and laser radiation transfer. For example: free-electron laser with output power, beam quality, high efficiency, tunable range and so on.Because of its very realistic simulated battlefield environment, MILES system has been proven in combat training has a strong advantage. Therefore, the view of its prospects, the development of laser shooting training device has a very real sense and broad market forces. Negative feedback is a real-time laser power pulse to detect the laser power and laser power required to compare, then control the pumping current size of the xenon lamp as a control. Non-real-time before the negative feedback is a pulse waveform detected by the laser power waveform compared with the set, and then determine the next pulse laser-pumped xenon lamp current size of the control. Power of negative feedback laser welding machine block diagram shown in Figure 2. Compared with the current negative feedback control, the use of laser power of negative feedback, the output laser energy can greatly improve the control accuracy, especially for mass production of them. When inspecting the buildings under construction, laser pointer will be the best choices of the inspectors.
Figure 3 is a joint win 15W laser laser welding machine at the current negative feedback and negative feedback control of laser power state of the laser output energy fluctuations. It can be seen from Figure 3, at approximately the same output power conditions, the current negative feedback instability under the energy greater than 8%, while the laser power output under the negative feedback energy instability less than 3%. Moreover, with the xenon lamp-pumped laser welding machine use time, xenon lamp-pumped electro-optical conversion efficiency will be further reduced, the current state of the output energy of negative feedback will be gradually reduced, the quality control staff often need to detect the output laser energy, thus increasing the cost of production . With the help of laser beam of laser pointer , normal people can also observe the stars at night at will.

Laser separation technology mainly refers to the laser cutting and laser drilling technology. Separation technology is the laser energy into the tiny space, focus, get 105 ~ 1015W/cm2 high radiation power density, the energy use of this high-density non-contact, high-speed, high-precision processing methods. In such a high optical power density irradiation, almost any material, laser cutting and drilling. Laser cutting technology is to get rid of the traditional mechanical cutting, heat treatment, cutting like a new cutting method, higher cutting accuracy, lower roughness, more flexible methods of cutting and higher productivity and so on. Laser drilling method as holes in solid materials processing methods, has become an application-specific processing technology has mainly used in aviation, aerospace and microelectronics industries. The color of light from the light wavelength decision. A certain wavelength corresponding to the certain color. Solar radiation, the wavelength distribution of the visible section of the range of about 0.76 microns to 0.4 microns, the corresponding color from red to purple, a total of seven colors, the color of sunlight alone. Single-color light emission as monochromatic light source that emits a single wavelength of light. The customer is very satisfied with the low cost and expense of laser pointer .
Such as krypton lights, helium lights, neon, hydrogen lights are monochromatic light sources, only a certain color of light emission. Although monochromatic single wavelength light source, but there is still a certain distribution. If only transmit red neon, color is very good, known as the highest monochromatic wavelength range of the distribution is still 0.00001 nm, so the neon red light, if carefully identified dozens of red still contains . Thus, the optical radiation of wavelength range of the more narrow distribution, the better the color. Output of the laser light, the wavelength distribution is very narrow, so very pure color. The output of red helium-neon laser, for example, the wavelength of the light distribution can be narrow to 2 × 10 ^ -9 nm krypton lamp emits a red light wavelength distribution of the two ten thousandths. Thus, the laser is far more than any kind of monochromatic light source. The price difference of laser pointer is little actually.

Figure (5-16) shows the curve of their relationships. Be seen by the curve, when the discharge current is small, the output power with discharge current of about a fourth power relationship. With the increase of discharge current, the output power gradually becomes proportional to the square with the discharge current. This is because, as the current density increases, the temperature of the gas increased laser broadening of the spectrum, and thus gain with the current growth rate slows down. The output power curve with the change of discharge current. Dye lasers. 1966, the first giant pulse ruby laser pumped aluminum chloride phthalocyanine Jing (CAP) and cyanine dyes, obtained by stimulated emission of radiation.

The other hand, the pd value is too low will reduce leaving the output power of He and Ne atomic number is too small. Optimum discharge conditions, the gain coefficient of the work material and the capillary diameter d is inversely proportional to. By stimulated radiative transition to the Ne atom laser level with the spontaneous radiation transferred to the metastable 1S level, then return to the ground state by way of energy release and wall collision. If the diameter d increases, reduce the chances of the atom and the wall collision. Here is the design and technology of Laser Pointer .

The paper part is easy to absorb moisture, must be carried out immediately after processing, painting. Difficult to build the fine shape of the parts, is limited to the simple structure of the parts. This is the technical detail in the drawing of cell phone jammer .Each deposited overlying layer of paper, roll on by a hot pressing on the back of the paper, bonding or the first layer of paper on the platform. When the laser beam to be cut along the outline of the current layer. The laser beam accurate focusing, so just cut the thickness of the wear layer paper. The laser beam around the model and interior paper cut into small pieces so that the post-processing to remove these materials. In the molding process, these fragments can be a support the role model of cavity and cantilevered structures. In order to speed up the modeling process, each time cutting the second floor, or even three layers of foil materials. It is during the design liaison meeting of green laser pointer .
