Mode-induced transverse photodarkening loss variations in large-mode-area ytterbium doped silica fibers

Transverse photodarkening loss variations in an LMA Yb-DCF are experimentally studied. Photodarkening rate depends on inversion, which is affected by the pump induced increase and signal induced depletion of the inversion. In double-clad fibers, intensity distributions of the pump and signal modes a...
