Uncompromising performance

The 793 nm 50 W High Power Fiber Coupled Diode Laser is a high-performance infrared engine engineered specifically for the resonant pumping of Thulium (Tm) and Holmium (Ho) doped active fibers. By providing a stable 50 W of continuous-wave (CW) output through a precision 105 µm fiber core, this module delivers the high energy density required for high-efficiency absorption in 2 µm laser architectures. Designed for long-term reliability in industrial and scientific environments, the K793 series features integrated 30 dB feedback isolation in the 1900 nm – 2100 nm spectral range. This critical technical safety feature shields the diode from the 2 µm return light inherent in Thulium systems, ensuring absolute component protection. With a superior 45% electrical-to-optical efficiency and a rugged industrial housing with FC-Ferrule termination, this module is the premier choice for medical surgical lasers, remote sensing, and advanced material processing.
