摘要

Tm:CaF_2 and Tm;Y:CaF_2 single crystals were prepared by the temperature gradient technique. The spectral properties of Tm;Y:CaF_2 single crystals were investigated and compared with those of Tm:CaF_2. It was demonstrated that codoping with Y~(3+) ions could efficiently improve the spectroscopic properties. Tm;Y:CaF_2 crystals have larger absorption cross-sections at the pumping wavelength, larger mid-infrared stimulated emission cross-sections, and much longer fluorescence lifetimes of the upper laser level(Tm~(3+):~3H_4 level) than Tm:CaF_2 crystals. Continuous-wave(CW) lasers around 1.97 μm were demonstrated in 4.0 at. % Tm,4.0 at. % Y:CaF_2 single crystals under 792 nm laser diode(LD) pumping. The best laser performance has been demonstrated with a low threshold of 0.368 W, a high slope efficiency of 54.8%, and a maximum output power of 1.013 W.
