摘　　要：To the best of our knowledge,this is the first time that a mid-infrared Er^(3+):CaF_(2)-SrF_(2) laser has achieved continuous-wave mode-locked operation by a semiconductor saturable absorber mirror.The laser emits a maximum output power of 93 mW at 2.73μm with a repetition rate of approximately 69 MHz and demonstrates a high signal-to-noise ratio of around 71 dB.In addition,a MgF_(2) birefringent plate was utilized to enable wavelength tuning of the Er^(3+):CaF_(2)-SrF_(2) laser,resulting in operation at approximately 2.73μm,2.75μm,2.79μm,and 2.81μm.These results demonstrate that Er^(3+):CaF_(2)-SrF_(2) is a promising alternative for the generation of efficient diode-pumped mode-locked lasers around 2.8μm.
