Uncompromising performance

The K976BNERN-530.0W is an ultra-high-power fiber-coupled module designed to serve as the high-brightness engine for next-generation industrial and scientific laser systems. Delivering a massive 530 W of continuous-wave output through a high-precision 200 µm fiber core, this module is engineered for applications where energy density and spectral purity are paramount. By utilizing integrated volume Bragg grating (VBG) technology, it maintains a narrowed 976 nm ± 1 nm center wavelength, providing unrivaled absorption efficiency for pumping high-power Ytterbium-doped fiber lasers.Built for rigorous industrial environments, the K976 series includes an integrated 30 dB feedback isolation system, shielding the diode from back-reflections during high-intensity materials processing. With a superior 45% electrical-to-optical efficiency and a robust thermal architecture, this module minimizes waste heat and ensures a long, stable operating lifespan. Housed in a heavy-duty industrial package with FC-Ferrule termination and precise thermal tracking, it is the premier choice for kilowatt-class fiber laser pumping, direct diode systems, and advanced additive manufacturing.
