976nm 250W Wavelength Stabilized Fiber Coupled Laser Diode

The 976nm center wavelength is high absorption peak for Yb-doped fiber laser. When the laser combined with VBG optics, the 976nm laser diode could be locked within +/-1nm, which performance is well suited for building efficient pumping skim in a non-stabilized environment in temperature, and is ideal for pumping very high power fiber lasers.
LumiMetriC provides a variety of fiber coupled laser diodes with wavelengths from 6xx-1100nm. The C18 series fiber coupled laser diodes are built with up to 18 single emitters of 10-20W power, and provide high power from 135µm or 200µm core fibers.
