摘要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 2.049μm with M2=1.1. The ZGP OPO can generate a total combined output power of 14.1W at 3.80μm signal and 4.45μm idler under pumping power of 28.7W. The slope efficiency reaches 61.8%, and M2=3.6 for OPO output is obtained.
