We report on our investigation of photo-darkening (PD)-induced thermal load in Yb-doped fiber lasers and the effective suppression by H2-loading. Compared with a quantum defect, the contribution of heat produced by PD was evaluated, indicating PD may

The radical elimination of photodarkening effect by H2-loading was demonstrated, and the output power was stable during long term operation in high power fiber amplifiers, without mode instability and photodarkening-induced core laser leakage.

In this work, deuterium loaded Yb-doped fiber has been proposed to mitigate mode instability in laser oscillator. Experimental results reveal that mode instability threshold power rises from ~459W to ~533W and ~622W at the condition of pristine fiber

The radical suppression of the photodarkening effect and laser performance deterioration via H 2 loading were demonstrated in high-power Yb-doped fiber (YDF) amplifiers. The photodarkening loss at equilibrium was 114.4 dB/m at 702 nm in the pristine
