Recently, relying on the Changchun Institute of Optics and Fine Mechanics, Changchun Institute of Optics and Fine Mechanics, Chinese Academy of Sciences successfully developed a compact all-solid-state semiconductor pump laser marking machine, much favored by the market. The successful development of the compact all-solid-state semiconductor pump laser marking machine will drive the development of the field of crystalline materials, semiconductor materials, optoelectronic devices and processes and the direct benefits and secondary benefits brought by it will serve as a platform for national economy and regional development To new vitality. Laser marking refers to the use of a laser beam to mark the surface material gasification or chemical and physical changes, which showed the way etching graphics and text. Compared with the traditional marking method, laser marking technology has the advantages of fast marking speed, clear and legible writing, little pollution, no wear, convenient operation, strong anti-counterfeit ability and high-speed automatic operation. As a result, laser marking has been widely applied to various processing fields, including hardware, metalware, precision machinery, auto parts, electronic devices, food packaging, knives, Gifts, watches, computer keyboards and other products, the surface, instead of the traditional marking technology, to inject new vitality into the product. At present, the laser marking machine according to different working methods can be divided into light pump YAG laser marking machine, semi-conductor pump laser marking machine, semiconductor pump laser marking machine, fiber marking machine. Among them, the semiconductor end pump laser marking machine can not only achieve more sophisticated marking effect, but also has the advantages of small size, low price. Changchun New Industry Photoelectric Technology Co., Ltd. developed a compact all-solid-state semiconductor pump laser marking machine, the light source using semiconductor arrays, high light conversion efficiency; the use of special coupling pump, the light source structure is more compact; low heat loss, No separate cooling system, is currently the smallest of similar products in the country.
