Uncompromising performance

The 793 nm 22 W High-Brightness Fiber Coupled Diode Laser is a technical-grade light source optimized for high-performance scientific and industrial pumping applications. Specifically engineered for the Thulium (Tm) and Holmium (Ho) absorption peaks, this module provides the energy density required to drive kilowatt-class 2 µm fiber laser systems with absolute spectral reliability. Delivering a robust 22 W of continuous-wave (CW) output through a precision 105 µm core, the K793 series maintains superior beam quality and coupling efficiency. To ensure system longevity, it features integrated 30 dB feedback isolation across the 1900 nm – 2100 nm range, shielding the diode from harmful back-reflections during the lasing process. Built with industrial-grade thermal management and a high-reliability FC-Ferrule termination, this module is the definitive engine for surgical medical platforms, directed energy research, and specialized materials processing.
