摘要

本文首次报道了由1.7 μm激光二极管泵浦的2 μm波段高效连续波声光调q Tm: LuAG激光器。当入射泵浦功率为28.2 W时，在2013 nm处的最大连续波输出功率为7.26 W，对应的斜率效率为38.5%，光效率为25.6%。在重复频率为1 kHz时，在AO调q模式下获得的最大脉冲能量为5.63 mJ，最小脉冲宽度为77 ns，对应的计算峰值功率为73.1 kW。此外，在最大输出功率下，x和y方向的m2因子分别约为1.9和1.7。

Efficient acousto-optically Q-switched Tm: LuAG laser end-pumped by a laser diode at 1.7 μm

We reported an efficient continuous-wave (CW) and acousto-optically (AO) Q-switched Tm: LuAG laser at 2 μm in-band pumped by a 1.7-µm laser diode for the first time. A maximum CW output power of 7.26 W at 2013 nm was achieved with an incident pump power of 28.2 W, corresponding to a slope efficiency of 38.5% and optical efficiency of 25.6%. With a repetition rate of 1 kHz, a maximum pulse energy of 5.63 mJ and a minimum pulse width of 77 ns were achieved under AO Q-switching regime, corresponding to a calculating peak power of 73.1 kW. Moreover, the M²-factors in x- and y-directions were measured to be about 1.9 and 1.7 at maximum output power, respectively.
