The 976 nm 27 W Wavelength-Stabilized Fiber Coupled Diode Laser is a high-performance source engineered for applications where spectral consistency and energy density are paramount. Delivering a stable 27 W of continuous-wave output through a precision 105 µm fiber core, this module provides the superior brightness required for high-efficiency pumping and advanced scientific research. Utilizing integrated Volume Bragg Grating (VBG) technology, the K976AAHRN series maintains an ultra-narrow 976 nm ± 0.5 nm center wavelength, ensuring maximum absorption in rare-earth-doped fibers. It achieves a superior 50% electrical-to-optical conversion efficiency, significantly reducing system heat load. For mission-critical protection, it includes integrated 30 dB feedback isolation, shielding the diode from back-reflections in high-power laser architectures. With its rugged industrial package and FC-Ferrule termination, it is the premier choice for stabilized fiber laser pumping and directed energy studies.
