采用单壁碳纳米管可饱和吸收体实现了二极管泵浦Nd：Lu0.33Y0.37Gd0.3VO4（Nd：LuYGdVO4）激光器的被动调Q输出。当泵浦功率为9.1W时，获得了最小脉宽52ns，最大峰值功率66.5W的激光输出。为了比较不同的增益介质，本文还研究了在同一激光腔下的Nd：LuVO4和Nd：Lu0.15Y0.85VO4（Nd：LuYVO4）被动调Q激光器。实验结果表明，Nd：LuYGdVO4晶体比Nd：LuVO4和Nd：LuYVO4晶体更适合于单壁碳纳米管可饱和吸收体被动调Q激光器。
A diode-pumped passively Q-switched Nd:Lu0.33Y0.37Gd0.3VO4 (Nd:LuYGdVO4) laser at 1.06 μm with a single-walled carbon nanotube saturable absorber is demonstrated. At the incident pump power 9.1 W, the minimum pulse width of 52 ns and the maximum peak power 66.5 W can be obtained. In order to compare different gain media, the passively Q-switched Nd:LuVO4 and Nd:Lu0.15Y0.85VO4 (Nd:LuYVO4) lasers under the same laser cavity are also investigated. The experimental results show that Nd:LuYGdVO4 crystal is more suitable for passively Q-switched laser with single-walled carbon nanotube saturable absorber than Nd:LuVO4 or Nd:LuYVO4 crystals.
