Lithium selenoindate (LiInSe2) crystals with high optical quality are successfully grown by small-angle inclined horizontal temperature gradient condensation. In order to evaluate the various characteristics, the powder X-ray diffraction (XRD) spectrum, optical damage resistance ability and Vickers hardness in lithium selenoindate crystals were studied. The growth crystals have orthorhombic nature, a = 6.184 Å, b = 7.092 Å and c = 8.207 Å. The damage thresholds of LiInSe2 crystal with the front face and back face were 224 mW/cm2 and 165 mW/cm2. Also the Vickers hardness number of LiInSe2 crystal was found to be 342.4 kg/mm2.
