Abstract :
The optical parametric oscillator based on the bulk crystal AgGaS2 with a two-pass pumping is created. Optical parametric oscillator pumped by the fixed wavelength 1.053 μm a compact nanosecond Nd:YAG laser. Pulse duration is 5-7 ns, a maximum pulse energy was 500 μJ at a frequency of 1-7 kHz. Lasing threshold from 12 to 20 mJ were obtained using an AgGaS2 crystal.
