Paper Abstract

We investigated photodarkening loss evolution and its reduction in Yb3+ doped aluminosilicate fibers utilizing 633 nm light irradiation. We demonstrate the final photobleaching value is intensity dependent, but the percentage of photodarkening reduction does not depend on dopant concentrations for settled bleaching intensity. We also show that the defects generated during the initial photodakening process have lower energy and can be effectively bleached by 633 nm photons while defects generated during photodarkening loss saturation cannot be bleached by low energy photons
