Optical parametrical oscillator, based on periodical polarized structure MgO:PPLN, is developed. Compact nanosecond Nd:YAG laser at 1.053mm has been used as a pumping source. Pulse duration is 5-7 nanoseconds at maximum pulse energy of 300mJ (1000-5000 Hz). The OPO threshold is 22mJ at 3 mm and 48mJ at 4.3 m. An optical-to-optical conversion efficiency varies within of 4-12.5% from incident pump power to the idler output.
