Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced 120w 940nm single bar laser chip. 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.
120W 940nm Single Bar Laser Chip
The 120W 940nm Single Bar Laser Chip uses electrical excitation as a pump source, semiconductor materials as a gain medium, and amplifies through resonant cavity mode selection, and then outputs lasers to complete the conversion of electrical signals to optical signals. This technology enables laser chips to realize the conversion of electrical energy to optical energy in various electronic devices, thereby exerting their functions
Applications:
• Laser Pumping • Medical • Materials Processing • Illumination
