ZnGeP2 optical parametric oscillator pumped by Ho∶YAG AO Q-switched laser is introduced. Pumped by a 1.9 μm laser, Ho∶YAG laser achieves 21.5 W laser with single wavelength and narrow line, under the condition of the Q-switch repetition frequency of 15 kHz. ZGP-OPO is pumped by the Ho∶YAG laser, yielding mid-infrared laser with an output power of 8.85 W and a pulse length of 15.3 ns. The slope efficiency of OPO is up to 80.9%. The laser has potential application in many fields such as gas detection and optoelectronic countermeasure.
