Passively Q-switched operation at 1.34 μm in which V:YAG was employed as saturable absorber has been demonstrated with a series of mixed Nd:GdxY(1-)xVO(4) crystals. The Q-switched laser pulse performance with these Nd-doped mixed vanadate crystals, especially Nd:Gd(0.63)Y(0.37)VO(4), was enhanced in respect to Nd:GdVO(4) under the identical conditions. The average output power of 171.3 mW with the shortest pulse width of 44.4 ns, largest single pulse energy of 21.7 μJ, and highest peak power of 489 W at the incident pump power of 5.04 W were obtained with Nd:Gd(0.63)Y(0.37)VO(4) crystal.
