Uncompromising performance

The 976 nm 60 W Wavelength-Stabilized Fiber Coupled Diode Laser is a high-precision source engineered for applications requiring extreme spectral consistency and high energy density. Delivering a potent 60 W output through a concentrated 105 µm fiber core, this module provides the superior brightness required for efficient pumping and materials processing. Utilizing integrated Volume Bragg Grating (VBG) technology, the K976AA5RN series maintains an ultra-stable 976 nm ± 0.5 nm center wavelength, making it one of the most reliable stabilized sources in its power class. It achieves a superior 50% electrical-to-optical conversion efficiency, minimizing heat load while maximizing diode life. For mission-critical protection, it includes integrated 30 dB feedback isolation (1020 nm–1200 nm), shielding the diode from back-reflections in high-power systems. With industrial FC-Ferrule termination and precise thermal tracking, it is the premier choice for scientific research and kilowatt-class fiber laser pumping.
