Uncompromising performance

The 976 nm 3 W Wavelength-Stabilized Fiber Coupled Diode Laser is a precision-grade light source engineered for high-end scientific research and fiber laser pumping applications requiring absolute consistency. Utilizing integrated Volume Bragg Grating (VBG) technology, this module maintains an exceptionally narrow 976 nm ± 0.5 nm center wavelength, ensuring high-efficiency absorption regardless of thermal or current fluctuations. Delivering a stable 3 W of continuous-wave output through a fine 105 µm fiber core, the K976AB2RN series provides superior beam quality and power density. With a high 50% electrical-to-optical efficiency and integrated 30 dB feedback isolation, this module is shielded against back-reflections in the 1020 nm–1200 nm range. Housed in a robust industrial package with FC-Ferrule termination, it is the definitive choice for precision laboratory spectroscopy and stabilized laser seeding.
