摘要：

We demonstrated a diode-end-pumped continuous-wave and passively Q-switched Nd:GdVO4 laser operating at 1.06 mum wavelength with a three-mirror folded resonator. The maximum continuous-wave output power of 8.18 W was obtained at the incident pump power of 22.5 W, with the corresponding optical conversion efficiency of 36.4%. For Q-switched operation, the maximum average output power was measured to be 4.64 W with the corresponding optical conversion efficiency of 25.8%, when the initial transmission of Cr4+:YAG crystal was 90%. The shortest pulse width of 83 ns, the largest pulse energy of 20.7 muJ and the highest peak power of 246.7 W were obtained when the Cr4+:YAG crystal with an initial transmission of 85% was used.
