分析了用于2 μm激光器的Tm：YAG陶瓷材料的特性。报道了二极管端面抽运Tm：YAG陶瓷激光器。在吸收泵浦功率为53.2W时，获得了17.2W的2016nm连续光输出，输出透过率为5%。光转换效率为32.3%，对应于36.5%的斜率效率。对于调Q操作，最短的宽度为69 ns的实现与脉冲重复频率为500 Hz，单脉冲能量为20.4 mJ，这表明优良的储能能力的Tm：YAG陶瓷。
Characteristics of Tm:YAG ceramic for high efficient 2-μm lasers are analyzed. Efficient diode end-pumped continuous-wave and Q-switched Tm:YAG ceramic lasers are demonstrated. At the absorbed pump power of 53.2W, the maximum continuous wave (cw) output power of 17.2 W around 2016 nm was obtained with the output transmission of 5%. The optical conversion efficiency is 32.3%, corresponding to a slope efficiency of 36.5%. For Q-switched operation, the shortest width of 69 ns was achieved with the pulse repetition frequency of 500 Hz and single pulse energy of 20.4 mJ, which indicates excellent energy storage capability of the Tm:YAG ceramic.
