我们首次展示了一种具有单壁碳纳米管可饱和吸收体（swcnts - sa）的可积被动调q (PQS) Tm，Mg: linbo3激光器。用不同的输出耦合器对其激光特性进行了研究。在泵浦功率为9.5 W时，在输出透射率为1%的情况下，在1963 nm附近获得了0.93 W的最大输出功率。光转换效率为9.79%，对应的斜率效率为17.4%。脉冲工作时，最短脉冲宽度为640 ns，脉冲重复频率为44.6 kHz，单脉冲能量为12.6 μJ。
We demonstrated an integratable passively Q-switched (PQS) Tm,Mg:LiNbO3laser with a single-walled carbon nanotube saturable absorber (SWCNT-SA) for the first time. Its laser characteristics were investigated with different output couplers. At the pump power of 9.5 W, the maximum output power of 0.93 W around 1963 nm was obtained with the output transmission of 1%. The optical conversion efficiency is 9.79%, corresponding to a slope efficiency of 17.4%. For pulsed operation, a shortest pulse width attained was 640 ns, with the pulse repetition frequency of 44.6 kHz, and the single pulse energy was 12.6 μJ.
