technology is developing increasingly which used in many fields, so the market demand for laser products is getting higher and higher. Ordinary laser products can not meet the needs of industry customers, which also urges laser manufacturers started to develop advanced laser product. Recently, Brandnew launched a new generation of laser products - 880nm QCW 300W semiconductor laser Chip.
In recent years, with the continued advancement of the “Made in China 2025” program, the application of laser technology in consumer electronics, smart equipment, PCB, robotics, artificial intelligence, LED laser processing, etc. has deepened. In 2017, China's laser processing market is nearly 500. 100 million yuan, an increase of over 28% year-on-year. It is expected that the laser market will reach 60 billion yuan in 2018, and the market development prospects are promising. Especially in the field of fine micro-machining, laser plays an irreplaceable role in the fields of drilling, engraving, grooving and surface treatment in photovoltaic, liquid crystal display, semiconductor, OLED and other fields, and is becoming an important pole leading the development of the industry.
Solid-state lasers for micromachining have a natural advantage. The strength of consumer electronics products and the development of new technologies will place higher demands on laser processing, and the characteristics of solid-state lasers make it a leader in competition with fiber lasers and carbon dioxide lasers. In all kinds of laser micromachining applications, microelectronics marking and chip micromachining still occupy a dominant position; domestic 3D printing technology is developing well and there is still huge room for appreciation; at the same time, UV laser marking will become Identify new growth points in the industry. In addition, with the development of diode pumping technology, the high beam quality, high power MOPA structure has become simple, solid-state lasers are increasingly used in various military radars such as direct detection and coherent detection. Brandnew's new 880nm QCW 300W semiconductor laser bar will be used primarily for military Ranging Radar and solid-state laser pumping.
Compared to CW, the peak power of the QCW laser diode bar will be higher. In addition, multiple high peak power QCW bars are packaged in the same area. These bars can be viewed as a single CW bar because each bar runs at a lower average heat loss when operating in QCW mode. These factors, combined with the ability to assemble a more compact diode array, allow for very high peak powers in QCW mode operation. Furthermore, QCW pumping can reduce the heat of the laser gain material, thereby effectively reducing the thermal bunching effect and improving the beam quality of the laser.
It is understood that Brandnew newly developed 808nm QCW laser chip conversion efficiency increased to 50%, output power 300W, fill factor: 75%, cavity length: 1500μm, very suitable for solid-state laser pumping and UV in the above fine processing field Laser.
