Uncompromising performance

The 888 nm 170 W High Power Fiber Coupled Diode Laser is a technically advanced pump source designed for high-performance scientific and industrial laser systems. By utilizing integrated Volume Bragg Grating (VBG) technology, this module maintains an ultra-stable 888 nm ± 1 nm center wavelength, providing the narrow spectral bandwidth required for maximum absorption efficiency in Nd-doped solid-state lasers. Delivering a potent 170 W of continuous-wave output through a high-precision 200 µm fiber core, the K888 series provides exceptional power density and beam quality. Engineered for maximum system safety, it features integrated 30 dB feedback isolation, shielding the diode from back-reflections during operation. With a high 47% electrical-to-optical efficiency and rugged HP-SMA905 termination, this module is the definitive choice for high-power DPSS laser pumping, scientific research, and advanced material processing.
