Second-harmonic generation in a uniaxial crystal in total-reflection geometry is precisely measured. A Y-cut plate and a Z-cut plate of quartz crystals were used as samples. The incident wave is totally reflected by a glass prism in contact with the sample crystal, and an evanescent wave penetrates into the sample as a fundamental wave. The results gave the quantitative values of the components for a nonlinear optical susceptibility tensor with various polarizations and with Y-cut and Z-cut quartz plates. This technique can be applied to various samples to evaluate their nonlinear optical efficiencies.
精确测量了全反射几何结构下单轴晶体中的二次谐波产生。使用石英晶体的Y切割板和Z切割板作为样品。入射波被与样品晶体接触的玻璃棱镜全反射，倏逝波作为基波穿透到样品中。结果给出了具有不同偏振以及Y切割和Z切割石英板的非线性光学极化率张量分量的定量值。该技术可应用于各种样品以评估其非线性光学效率。
