976nm 18W Wavelength-Locked Fiber Coupled Diode Laser (K976AAHRN-18.00WN1N-10522F20EFF, Standard)
The K976AAHRN-18.00WN1N-10522F20EFF is a 976nm 18W wavelength-locked fiber-coupled diode laser from BWT. It delivers a minimum 18W output power through a 105μm core / 0.22NA multimode fiber (2.0m length, 0.9mm jacket, FC bare ferrule). The module features precise wavelength locking at 976±0.5nm with a narrow 0.5nm (FWHM) spectral width, 50% typical electro-optical efficiency, and built-in anti-reflection protection (30dB isolation) for the 1020~1200nm band. Housed in a compact gold-plated 4-pin package with mounting flanges and optional thermistor, it operates at a typical 12.0A / 3.2V with a base plate temperature of 23~27°C. All data are tested at nominal output power at 25°C under non-condensing conditions.
