Second harmonic generation for wavelengths between 2.3 μm and 6 μm and optical parametric generation from 5 μm to 12 μm in mid-infrared (IR) were demonstrated in a nonlinear crystal, LiInS2. Single crystals with diameters upto 20 mm and lengths upto 40 mm were grown. The band gap values and crystal type were found to be identical for all crystals although small variations in lattice parameters due to point defects were observed. The crystal exhibited wurtzite-type structure avoiding anisotropy in the thermal expansion. The crystal also possesed superior thermal conductivity and larger band edge allowing for high-intensity short pulse pumping at wavelengths as short as 800 nm without the onset of two-photon absorption.
