K878BL9RN-170.0W
The K878BL9RN-170.0W is an 878.6nm, 170W high-power wavelength-stabilized fiber-coupled diode laser module. It delivers a minimum of 170W continuous output power from a 200μm core, 0.22NA multimode fiber terminated with an HP-SMA905 connector. Wavelength locking ensures a narrow spectral width of 0.5nm (FWHM) and a low wavelength temperature drift of 0.03nm/℃, making it ideal for wavelength-sensitive pumping. The module offers up to 47% electro-optical conversion efficiency, integrated anti-reflection protection (1020-1200nm, 30dB isolation) against back-reflected light, and a compact 80×76×15mm package with a simple two-pin interface. All specifications are measured at 170W output power and 25℃ baseplate temperature under non-condensing conditions.
