Abstract

The excited state lifetime of Er³⁺ and gain coefficient of an Er³⁺/Yb³⁺ co-doped phosphosilicate optical fibre with and without hydrogen loading can be recovered and even improved by high temperature annealing. Consequently processes optimizing room temperature component fabrication such as hypersensitisation are found to offer no added value for high temperature operation. The implications for harsh environmental laser performance are discussed.
