摘要：
A high power, efficient, and tunable laser source in the 8-10 mu m wavelength range, based on a ZnGeP2 (ZGP) optical parametric oscillator (OPO) pumped by a hybrid 2-micron-laser, is demonstrated. Tuning to 9.8 mu m was achieved, and with 8.9 W of 2.1 mu m pump power we obtained 0.95 W at 8 mu m with an M-2 value of 2.7 from an OPO with two walk-off compensating crystals. More than 40% quantum efficiency was achieved.
