We report a high power and high efficiency double resonant ZnGeP2 (ZGP) optical parametric oscillator (OPO) pumped by a Tm,Ho:GdVO4 laser. We employ a Tm, Ho: GdVO4 laser as the pump source operated at 2.049 mu m with M-2 = 1.1. The ZGP OPO can generate a total combined output power of 14.1 W at 3.80 mu m signal and 4.45 mu m idler under pumping power of 28.7 W. The slope efficiency reaches 61.8%, and M-2 = 3.6 for OPO output is obtained.
