976nm 27W Wavelength-Locked Fiber-Coupled Diode Laser (K976AAHRN-27.00WN1N-10522F20EFF)
The K976AAHRN-27.00WN1N-10522F20EFF is a 976nm 27W wavelength-locked fiber-coupled diode laser developed by BWT. It delivers stable high-brightness output through a 105μm/0.22NA multimode fiber, featuring a precisely locked center wavelength of 976±0.5nm, a narrow spectral width of 0.5nm (FWHM), a typical power conversion efficiency of 50%, and built-in anti-reflection protection over the 1020~1200nm band with 30dB isolation. Housed in a compact 4-pin gold-plated package with an optional thermistor, it is an ideal pump source for fiber lasers and scientific research applications.
