摘要

只提供摘要形式。几年前，人们发现了主要由二次谐波产生(SHG)引起的级联/spl chi//sup(3)/二阶效应(CSOE)的组合有可能增加/spl chi//sup (3)/ Kerr效应的幅度。最近的研究表明，光整流和线性电光效应的组合过程会导致类似的现象。随后，我们证明了ZnTe立方晶体的时间行为，并评估了三阶和CSOE对有效非线性折射率n/sub 2/的贡献幅度。

Comparison of /spl chi//sup (3)/ and cascaded /spl chi//sup (2)/ contributions to the nonlinear index of refraction of a cubic crystal: Influence of optical rectification

Summary form only given. Some years ago the potential of increasing the magnitude of /spl chi//sup (3)/ Kerr effect with a combination of cascaded /spl chi//sup (3)/ second order effects (CSOE) mainly due to second harmonic generation (SHG) was discovered. It has recently been shown that the combined processes of optical rectification and linear electro-optical effect lead to a similar phenomenon. Hereafter we evidence in a ZnTe cubic crystal, the temporal behavior and evaluate the amplitudes of both third-order and CSOE contributions to effective nonlinear index of refraction n/sub 2/.
