We measure the birefringence of the nonlinear optical (NLO) properties of cadmium silicon phosphide via the Z-scan technique at near and mid-infrared wavelengths. We discuss the implications of the NLO properties on optical parametric amplifier performance. We find that the nonlinear absorption does reduce the conversion efficiency, while the nonlinear refraction has a negligible effect.

CdSiP2 在近红外和中红外波长的非线性光学测量

我们通过 Z 扫描技术在近红外和中红外波长处测量了磷化硅的非线性光学 (NLO) 特性的双折射。我们讨论了 NLO 特性对光参量放大器性能的影响。我们发现非线性吸收确实降低了转换效率，而非线性折射的影响可以忽略不计。
