摘要

We report a high power and high efficiency double resonant ZnGeP2 (ZGP) optical parametric oscillator (OPO) pumped by a Tm,Ho:GdV04 laser.We employ a Tm,Ho:GdVO4 laser as the pump source operated at 2.049 μm with M2=1.1.The ZGP OPO can generate a total combined output power of 14.1 W at 3.80 μm signal and 4.45 μm idler under pumping power of 28.7 W.The slope efficiency reaches 61.8%,and M2 = 3.6 for OPO output is obtained.
