Sažetak
This paper reviews and extends the work done on photodarkening by our project consortium and present our latest results on bleaching and photodarkening mitigation in fiber lasers. We shows the need for a standard set-up to avoid underestimation of photodarkening equilibrium losses and we suggest photodarkening losses scale with the square of Yb doping level. Investigation on visible light emission suggest an interplay of visible light with the Yb excited level. Finally we present an extensive investigation of photobleaching, both as post-irradiation and as simultaneous bleaching. We show evidence photobleaching can effectively mitigate the impact of photodarkening on laser performance when highly-doped Al-silicate fibers are used.
