[摘要]：A diode-pumped passively Q-switched Nd:Lu(0.33)Y(0.37)Gd(0.3)VO(4) (Nd:LuYGdVO(4)) laser at 1.06 mu m 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: LuVO(4) and Nd:Lu(0.15)Y(0.85)VO(4) (Nd:LuYVO(4)) lasers under the same laser cavity are also investigated. The experimental results show that Nd: LuYGdVO(4) crystal is more suitable for passively Q-switched laser with single-walled carbon nanotube saturable absorber than Nd: LuVO(4) or Nd: LuYVO(4) crystals.
