Abstract

We demonstrate optical parametric oscillators based on the wide band-gap (3.76 eV) LiGaS2 (LGS), pumped by 100-Hz/8-ns and 1-kHz/1-ns laser sources at 1064 nm. Notwithstanding the modest second order nonlinearity of this material singly resonant operation was possible due to the high optical damage resistivity of LGS. Idler pulses near 5.46 μm were generated with an energy of 134 μJ and duration of 5.4 ns in the first case and energy of 1.1 μJ and sub-nanosecond duration in the second case. We present also optical surface damage measurements at 1064 nm using 14-ns pulses.
