摘要：

We report on the laser emission of erbium-doped fluoride glasses in the spectral range from 2.7 to 2.8 mu m. The pump source was a fiber-coupled InGaAs semiconductor laser emitting near lambda(p) similar to 970 nm. The laser performance of bulk samples with various ErF3 contents was investigated with respect to the optimum doping concentration, which is estimated to be higher than 8 mol. %. A maximum output power of P-out > 160 mW and a slope efficiency of eta = 10% were achieved. Results are compared with previously published data on erbium-doped ZBLAN fiber and LiYF4 crystal lasers.
