Uncompromising performance

The 915 nm 12 W Fiber Coupled Diode Laser is a high-performance light source engineered for reliability in industrial pumping and scientific research. Delivering a stable 12 W of continuous-wave output through a precision 105 µm core, this module provides the energy density and beam quality required for high-efficiency system integration. Featuring a superior 50% electrical-to-optical conversion efficiency, the K915 series minimizes thermal management complexity while maximizing the diode’s operating life. For advanced system protection, it includes integrated 30 dB feedback isolation in the 1020 nm–1200 nm range, shielding the diode from back-reflections in complex optical architectures. Built in a robust industrial package with high thermal stability, it is the definitive choice for ytterbium-doped fiber laser pumping and advanced spectroscopy applications.
