Centralized Disposition of green laser pointer

At this point you can combustion oxygen, and provide a lot of heat, such as the cutting speed. Continuous output laser cutting is preferred. Features: Laser cutting can be especially hard, brittle, and special features of soft materials, the melting point of difficult materials; kerf width is very narrow; cutting surface smooth; cutting the heat-affected surface layer of light, the surface stress is small; cutting speed, heat-affected zone small; no mechanical deformation, no tool wear, easy to automate production. More green laser pointer will be bought for the party atmosphere.

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.
