9W 976nm 2nm FWHM Fiber Coupled Diode
- 976nm 9W CW, high electro-optic conversion efficiency.
- Wavelength-stabilized narrow 2nm FWHM spectral linewidth.
- 105μm fiber coupling structure, high coupling efficiency.
- Fiber Laser & Fiber Amplifier Pump Source: The narrow stabilized spectrum greatly improves pumping absorption efficiency, reduces heat generation of gain fiber.
- Solid-State Laser Excitation Light Source: Perfect pump for Ytterbium-doped solid laser crystals, boosting overall laser conversion efficiency and output stability.
- High-Precision Optical Spectral Experiment: Stable narrowband infrared light source for material spectrum testing, optical laboratory research and instrument calibration.

This 9W 976nm fiber coupled laser diode features wavelength locking technology with only 2nm FWHM linewidth and 105μm fiber output. It solves the wavelength drift issue of ordinary pump diodes, delivers stable spectrum and power, and has outstanding heat resistance. Widely applied as high-efficiency pump source for fiber lasers, solid-state lasers, as well as optical research and industrial thermal processing equipment.
