Hangzhou Brandnew Technology Co., Ltd. is one of China's leading manufacturers and premier suppliers of advanced 500mw 638nm unmounted 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.
500mW 638nm Unmounted Laser Chip
Laser chip, also called unmounted diode laser bar, is single-emitter laser chip or single-bar laser chip, which are not mounted to a heat sink and lack any exterior packaging. Select from GaAs, InP, and GaSb unmounted diode laser bars and chips to get output from 450 nm to 2 µm, which deliver exceptional reliability and performance.
