Abstract
We report on continuous-wave (CW) and rhenium diselenide (ReSe2) Q-switched dual-wavelength mid-infrared (MIR) laser performances of Er:YAP crystal in this Letter. Under an absorbed pump power of 5.5 W, a maximum CW Er:YAP laser output power of 1.02 W is obtained, corresponding to a slope efficiency of 25.3%. With multilayer ReSe2 material as a saturable absorber, a stable Q-switched Er:YAP crystal laser with dual-wavelength output of 2.73 and 2.80 μm is realized for the first time, to the best of our knowledge. The nonlinear optical measurements of the multilayer ReSe2 reveal efficient saturable absorption properties around 3 μm showing a modulation depth of 7.5% and a saturation intensity of 14.5 μJ/cm2. The maximum Q-switching output power reaches 526 mW, and the corresponding laser power jitter is around 3% in 1 h. The shortest pulse duration and the highest pulse repetition rate are 202.8 ns and 244.6 kHz, respectively. These results prove that Er:YAP crystal could be a reliable laser crystal for MIR solid-state lasers.
