Lasers currently used mostly YAG laser, CO2 laser-based

Lasers currently used mostly YAG laser, CO2 laser-based.
Laser coating: in aerospace, mold and electrical industries widely. Currently used lasers to high power multi-YAG laser, CO2 laser-based.
Based on laser applications in dentistry different roles, is divided into several different laser systems. Distinction is an important feature of the laser: the wavelength of light, different wavelengths of laser on the role of different organizations in the visible and near infrared spectral range of light absorption is low, penetrating and strong, can penetrate into the tooth structure more deep parts, such as argon ion laser, diode laser or a Nd: YAG laser (Figure 1). Laser Pointer  has developed into a pint-sized high-tech product. The Er: YAG laser and the CO, laser light penetration is poor, can only penetrate the tooth structure about 0.01 mm. Difference between the two lasers is an important feature: the laser intensity (ie, power), as applied in the diagnostics of laser diode, the intensity of only a few milliwatts, which is sometimes used in the laser display.
For the treatment of the laser, usually a few watts of moderate-intensity laser. Laser organizations, and also depends on the laser pulse emission mode, the typical way a continuous pulse laser emission are: argon ion laser, diode laser, CO2, laser; to launch short-pulse laser are: Er: YAG laser or many of the Nd: YAG laser, short pulse laser intensity (ie, power) can be up to 1,000 watts or more, these high strength, high absorption of laser light is also only applies to clear the hard tissue.the use of laser in the beauty industry more widely. Laser Pointer  is not only an instrument for pointing but also extending continuously. Laser is to produce high energy, focus precisely, a certain penetration of monochromatic light, the role of human tissues and locally produced high heat to achieve the removal or destruction of the target organization's purpose, laser pulses of different wavelengths to treat the types of vascular and pigmented skin, such as nevus of Ota, port wine stains, freckles, age spots, telangiectasia, as well as to tattoo, eye line, eyebrow, scar treatment, etc.
Ordinary light is light in all directions. Let the light emitted towards one direction, you need to light a certain condenser fitted with devices such as car headlights, and searchlights were installed on the role of the condenser mirror, so that radiation is to bring together in one direction injection. Laser emission of the laser, born in one direction injection, beam divergence is extremely small, only about 0.001 radians, nearly parallel. Some enterprises have purchased page-turning  Laser Pointer .In 1962, the first human use of laser irradiation the moon, the moon's distance from the Earth about 38 million km, but the laser spot at the lunar surface less than two kilometers. If condenser works well, seemingly parallel light beam searchlight shooting the moon, according to its spot diameter will cover the entire moon.

Important features: the laser has four important features. High directivity (ie, high directivity, the speed of light divergence angle is small), the laser beam in an extended range of a few kilometers away, but a few centimeters; high color than ordinary light 10 times more than the width of the frequency of the laser; high brightness, the use of laser The beam convergence can produce up to several million degrees of temperature. Coherence, the two beams overlap, resulting in light and dark to understand the fringes (monochromatic) or colored stripes (natural light) phenomenon is called interference of light. Only the same frequency and direction of vibration, phase equal or week difference between the two constant beam of light that has coherence. Applications - the use of laser with high directivity, high color and high brightness, and other characteristics can be contact-free long-distance measurement.Ie: where: L - measuring sites A and B, between two points distance; c - the speed of light propagation in the atmosphere; t - light from the A, B, once the time required. To measure the A, B, distance to measure the light propagation time t, according to different methods of measuring time, the laser range finder is usually divided into two kinds of phase and pulse measurements in the form of the above equation.

But it is generally inconvenient modulation wavelength, and the heating power by the working substance restrictions. The use of synchrotron radiation produced electron in circular motion and a continuous spectrum of radiation, but the broad-spectrum radiation by spectrophotometry, the color intensity is greatly restricted, and non-coherent light. Synchrotron Radiation Facility in decades gone through three generations of development, because it has a wide range of applications, either the world and has dedicated more than 70 devices, with a total investment estimated at more than $ 1 billion. In order to better meet the application requirements, it is the shorter pulse, better coherence, the fourth generation of a higher degree of development of Yao. The following will be presented free-electron laser (later referred to as FEL), it is with these characteristics, a new light source, so the fourth-generation FEL is also known as synchrotron radiation. The advantage of laser pointer price will help the company win the order of laser pointer .
The scope of work in the light most use of radio frequency FEL linear accelerator to provide electronic sources. Its working principle can be summarized as follows. High-energy electrons generated by the accelerator by the deflection magnets alternate in polarity injected into the wiggler. Electronics for doing torsion movement of electromagnetic radiation (light pulses), the downstream and upstream optical pulses by two mirrors and reflections after the recurring role of the electron bunch. The result is movement along the direction of electron clusters into a size smaller than the wavelength of the tiny bunches. These micro-bunches to their kinetic energy into light energy field, increase the amplitude of the light field. This process is repeated several times until the light intensity reached saturation. After the effects of electron deflection magnet is deflected by the lower outside the system. The customer has noticed the advantage of laser pointer price of this laser pointer company.
These are the FEL produces a description of the image comparison process. From the physics point of view, this process is the electron emission stimulated Compton scattering results. Here one of the most critical aspect is to gather as many electronic shorter than the wavelength of the bunch.

Should be noted that cutting the workpiece and the nozzle pressure Pc is a function of distance. As the oblique shock wave reflection at the air border many times, so cutting pressure cyclical changes. The first high-pressure zone near the cutting nozzle, the nozzle exit surface to a distance of about 0.5 ~ 1.5mm, cutting a large and stable pressure Pc, is the cutting lever commonly used in industrial production process parameters. The second area of high pressure cutting nozzle exit of about 3 ~ 3.5mm, cutting pressure Pc is also large, can also achieve good results, and help protect the lens, to improve their life. Curve on the other high-pressure area due to cutting too far away from the nozzle exit, is difficult to match with the focused beam can not be used. In summary, CO2 laser cutting technology is China's industrial production has been more and more applications, research and development abroad is higher cutting speed and cutting thicker steel technology and equipment.

 Another type of laser pointer will be demonstrated in the next passage.
The following were introduced in accordance with the latter classification ranging pulse ranging and phase. Ranging laser pulse. The laser pulse ranging principle. Because the speed of light is constant, the light propagation along the straight line, by measuring the beam round-trip propagation time in the test distance can be calculated straight-line distance between two points. Laser pulse ranging principle is controlled by a laser pulse timer to open the door to receive the returned laser pulse control timer closed, measure the round-trip propagation time of the laser beam in the test distance to complete the distance measurement. The formula is: where d is the test distance; c is the velocity of propagation of the laser in the atmosphere; t is the round-trip propagation time of the laser in the test distance. It is the concept of laser pointer .
