Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced 12w 976nm laser bars and chips. Operating a state-of-the-art factory, we specialize in the entire production spectrum—from high-performance chips, TO/F/C Mounts, COS, and MCC bars, to robust stacks and advanced fiber-coupled solutions.
12W 976nm Laser Bars and Chips
12W 976nm Laser Bars And Chips are produced under the strictest quality controls. We work only with state-of-the-art epitaxy, processing, and facet coating technology. Standard soldering methods are used for assembling laser chip. The material supports both soft solder (indium) and hard solder (gold/tin). The standard configuration of the laser chip is an emitter structure separated on the p-side. On request, laser chips are available with continuous p-side metallization and adapted facet coatings, using low AR coatings for the assembly of external resonators
