976nm 240W Fiber Coupled 105um Diode With Narrow Tolerance
Features:
- Narrow wavelength tolerance of ±1nm for stable pumping.
- 240W high power delivered via 105μm, 0.18NA bare end fiber.
- Spectrum width less than 1nm to reduce pump source noise.
Applications:
- Used as high-power pump source for ytterbium-doped fiber lasers and solid-state lasers.
- Applied in industrial metal cladding, surface hardening and laser heat treatment processes.
- Suitable for laser plastic welding and polymer material thermal processing equipment.
- Deployed in scientific research systems requiring narrow spectrum high brightness pumping.

This 976nm 240W fiber coupled diode laser features tight wavelength tolerance and ultra-narrow spectral width. Equipped with 105μm core bare end fiber (0.18NA), it provides stable high-brightness laser output. It works reliably at 25℃ test condition, supporting wide storage temperature range. It is an ideal high-power pumping laser diode for industrial laser systems and photonics research.
