摘要：

The comparison on performance of passively Q-switched laser properties of continuous-grown composite GdVO4/Nd:GdVO4 and YVO4/Nd:YVO4 crystals under direct pumping to the emitting level was demonstrated. A Cr4+:YAG crystal was used as saturable absorber. At an incident pump power of 10 W, the average output power, the pulse width, the repetition rate, the pulse energy, and the peak power for a GdVO4/Nd:GdVO4 laser were 1.22 W, 48.1 ns, 121 kHz, 10.1 mu J, and 209.6 W, respectively. And for a YVO4/Nd:YVO4 laser under the same conditions, these output characteristics were 1.26 W, 44.9 ns, 218 kHz, 5.8 mu J, and 128.7 W, respectively. (C) 2011 Optical Society of America
