The 808 nm 150 W High Power Fiber Coupled Diode Laser is a robust, high-intensity laser source engineered for the most demanding industrial and medical applications. By targeting the industry-standard 808 nm wavelength, this module provides the optimized spectral overlap required for high-efficiency pumping of Nd:YAG and Nd:YVO4 solid-state lasers. Delivering a massive 150 W of continuous-wave output, the K808 series is built with a high-brightness 200 µm or 400 µm fiber core (0.22 NA), ensuring exceptional beam quality and power density. For maximum system reliability in industrial environments, the module features integrated 30 dB feedback isolation, protecting the diode from harmful back-reflections in the 1020 nm–1200 nm range. With an industrial-grade thermal design and a standard SMA905 termination, this module is the definitive engine for multi-kilowatt laser systems, surgical medical platforms, and high-speed material processing.
