Temperature dependence of photodarkening kinetics

We report on the characterization of photodarkening (PD) kinetics at Yb-doped fiber samples, inducing the PD loss by core-pumping at 975 nm with respect to different fiber temperatures in the range of 77 to 770 K. The thermal dependency of important PD parameters is presented. Additionally, we introduce a phenomenological model to include thermal and recovery effects in the description of the PD loss evolution and to improve the understanding of the PD process.
