Abstract

The orthorhombic biaxial crystal BaGa 4 S 7 has been employed in a 1064 nm pumped optical parametric oscillator generating < 6 ns long idler pulses with energies as high as 0.5 mJ at 6.217 μm and average power of 50 mW at 100 Hz. Notwithstanding the relatively low nonlinearity, 3 times above threshold operation has been achieved at pump intensities more than 5 times below the crystal surface damage limit.
