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 μm 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 μm by transmitting the OPO parameters, corresponding to an idler laser slope efficiency of 12.1%.
