Investigation of Photo-Darkening-Induced Thermal Load in Yb-Doped Fiber Lasers

We report on our investigation of photo-darkening (PD)-induced thermal load in Yb-doped fiber lasers and the effective suppression by H 2 -loading. Compared with a quantum defect, the contribution of heat produced by PD was evaluated, indicating PD may become the primary heat source. To reduce the h...
