Abstract :
Describes the efficient 2 mu m operation of a monomode Tm3+-doped silica-based fibre laser pumped with a Nd:YAG laser at 1.06 mu m. The maximum fibre laser output power was 51 mW at 2.038 mu m for an absorbed pump power of 230 mW. The threshold power was 60 mW absorbed and the slope efficiency with respect to absorbed power was 30%.
