通过主平面内和主平面外的二次谐波产生，我们估计了与LiInS2和liinsse2同结构且具有更大带隙的含锂中红外晶体LiGaS2和LiGaSe2的三个非线性系数。光学参量放大的第一个结果揭示了它们直接下转换到中红外的优势。
By second harmonic generation in and out of the principal planes we estimated the three nonlinear coefficients of the Li-containing mid-IR crystals LiGaS2 and LiGaSe2 which are isostructural to LiInS2 and LiInSe2 and possess even larger bandgaps. First results on optical parametric amplification reveal their advantages for direct down conversion to the mid-IR.
