摘要：

We report a high-power, long-wavelength infrared ZnGeP2 (ZGP) optical parametric oscillator (OPO) pumped by a Q-switched Tm, Ho: GdVO4 laser. The wavelength tuning range of 7.8-9.9 mu m is realized by rotating the external angle of the ZGP crystal. We obtain an output power over 30 mW across the whole wavelength range and achieve a 1.71 W output power at 8.08 mu m by transmitting the OPO parameters, corresponding to an idler laser slope efficiency of 12.1%.
