Experimental verification of spatial distribution of photodarkening in large mode area ytterbium doped fibers

We experimentally demonstrated that photodarkening is not uniformly distributed in the cross-section of bent LMA fibers. Photodarkening distribution depends on coiling diameter, and affects the use of fibers in applications and their photodarkening propensity measurement.
