The 976nm center wavelength is high absorption peak for Yb-doped fiber laser. The 976nm fiber coupled laser modules adopted multi-single-emitters structure and output 260W high power from 135µm core fiber, which is ideal for pumping 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.
