We directly measured the second harmonic generation and difference frequency generation phase-matching directions of the nonlinear crystal CdSiP(2) until 9.5 μm using the sphere method. The simultaneous fit of the experimental angular data allowed the Sellmeier equations of the ordinary and extraordinary principal refractive indices to be refined over the entire transparency range of the crystal.
我们使用球方法直接测量了非线性晶体 CdSiP(2) 的二次谐波产生和差频相位匹配方向,直至 9.5μm。实验角数据的同时拟合允许在晶体的整个透明范围内细化寻常和非常主折射率的Sellmeier 方程。
