CO2 laser marking machine laser material mixed gas as CO2 laser wavelength and its main application is 10.6μm. Due to the high conversion efficiency of this type of laser laser, laser operation while the heat generated by convection or diffusion can be passed quickly to the laser gain region outside its laser average output power can do very high levels (above megawatts) to meet High-power laser processing requirements.
High-power CO2 laser for laser machining and abroad, mainly cross-flow, axial flow lasers. ① cross-flow laser: cross-flow laser beam quality is not very good, multimode output, mainly used for heat treatment and welding. Our country has been able to produce a variety of high-power transverse flow CO2 laser series, can meet the domestic demand for laser heat treatment and welding. ② axial flow lasers: axial flow laser beam quality is better, for the fundamental mode or quasi-fundamental mode output, mainly for laser cutting and welding, laser cutting equipment Our market is mainly occupied by a foreign axial flow lasers. Although domestic manufacturers in foreign axial flow lasers lasers do a lot of work, but because of the need to import the main parts, a significant decline in prices is difficult, the penetration rate is low.
  Mold surface treatment has been valued in the field of machining problems. With the development of new technologies, there are many traditional approach is not applicable. Complex shape of the mold, the ideal surface treatment is carried out with a laser, it is almost no distortion, surface hardness than the hardness of conventional treatment is high, and more wear and last longer.
