摘要：

采用光浮区法生长了掺铥钇镓石榴石(Tm:Y3Ga5O12, Tm:YGG)激光晶体，探索了Tm:YGG晶体的光学性能，测试了其室温吸收谱并计算了吸收截面和发射截面。使用中心波长为795 nm的激光二极管作为泵浦源，实现了Tm:YGG晶体的连续激光输出，得到了波长为2 012.8 nm的激光，阈值为0.515 W，斜效率为9.9%，光光转换效率为9.3%。结果表明Tm:YGG晶体在2 μm波段可能有好的应用前景。

Tm3+ doped yttrium gallium garnet (i.e., Tm:Y3Ga5O12, Tm:YGG) laser crystal was grown by an optical floating zone method. The optical properties of the Tm:YGG crystal was investigated. The absorption cross section and emission cross section were calculated based on the absorption spectra of the Tm:YGG. When pumped by a 795 nm laser diode, a continuous-wave Tm:YGG laser at 2 012.8 nm was realized at a threshold of 0.515 W, a slope efficiency of 9.9% and an optical conversion efficiency of 9.3%. The experimental results show that the Tm:YGG crystal is a potential material for the laser at 2 μm.
