976nm 530W Wavelength-Locked Fiber Coupled Semiconductor Laser (K976BNERN-530.0WN0N-20022F20EFF)
The K976BNERN-530.0WN0N-20022F20EFF is a high-power, wavelength-locked fiber coupled semiconductor laser developed by BWT. It delivers a minimum output power of 530W at a center wavelength of 976±1nm through a 200μm core / 0.22NA multimode fiber with an FC bare ferrule connector. Featuring a narrow spectral width of 0.7nm (FWHM), 50% typical power conversion efficiency and built-in anti-reflection protection over 1020~1200nm with 30dB isolation, this module is specifically designed as a reliable, stable pump source for fiber lasers. The laser operates at a typical current of 26.0A and voltage of 42.0V, with a wavelength temperature coefficient of only 0.02nm/°C, ensuring excellent wavelength stability. It is housed in a compact 172×70×21mm package with 4 mounting holes and 2 electrode pins, and requires base plate temperature control within 23~27°C.
