✦ Synopsis

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: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:LuVO4 or Nd:LuYVO4 crystals.
