LiInS2是一种AIBIIIC2VI三元半导体，结晶具有mm2对称性。有用的透明度范围是 0.5–8 μ，我们在该范围内测量了折射率。还测量了二次谐波产生的光学非线性系数。非线性品质因数与 AgGaS2 相当。 LiInS2 中可以实现三频共线相位匹配，并对其进行了详细分析。 LiInS2 被认为是比类似化合物 LiGaO2 更有用的潜在光学非线性材料。
LiInS2 is an AIBIIIC2VI ternary semiconductor crystallizing with mm2 symmetry. The useful transparency range is 0.5–8 μ, over which we have measured the refractive indices. The optical nonlinear coefficients for second harmonic generation have also been measured. The nonlinear figure of merit is comparable to that of AgGaS2. Three‐frequency collinear phase matching is possible in LiInS2 and is analyzed in some detail. LiInS2 is judged to be a potentially more useful optical nonlinear material than the analogous compound LiGaO2.
