The linear and second-order nonlinear optical properties of single-crystal zinc tris(thiourea) sulfate, or ZTS, are determined. The deduced nonlinear coefficients are |d(31)| = 0.31, |d(32)| = 0.35, and |d(33)| = 0.23 pm/V compared with a |d(14)| value of 0.39 pm/V for potassium dihydrogen phosphate. Because it exhibits a low angular sensitivity (deltaDeltak/deltatheta), ZTS may prove useful for type-II second-harmonic generation from 1.06 to 1.027 microm. We present the phase-matching measurement data for ZTS and compare the calculated frequency conversion efficiency for ZTS with that of several other well-characterized materials.
测定了单晶硫酸三（硫脲）锌（ZTS）的线性和二阶非线性光学性质。推导得到的非线性系数为|d(31)| = 0.31、|d(32)| = 0.35和|d(33)| = 0.23 pm/V，而磷酸二氢钾的|d(14)|值为0.39 pm/V。由于ZTS表现出较低的角度灵敏度（deltaDeltak/deltatheta），它可能在1.06至1.027微米的II型二次谐波产生中有用。我们给出了ZTS的相位匹配测量数据，并将ZTS的计算频率转换效率与其他几种特性良好的材料进行了比较。
