We demonstrate a continuous-wave 2.1-µm laser with a new Ho:GdTaO crystal pumped by a 1940.3-nm Tm fiber laser at room temperature. The maximum output power of 11.2 W at 2068.39 nm was achieved, corresponding to a slope efficiency of 72.9%. Moreover, the beam quality factor was measured to be about 1.4 at the maximum output level.
我们展示了一种连续波2.1微米激光器,它采用新型Ho:GdTaO晶体,在室温下由1940.3纳米的Tm光纤激光器泵浦。在2068.39纳米处实现了11.2瓦的最大输出功率,对应斜率效率为72.9%。此外,在最大输出水平下测得光束质量因子约为1.4。
