Femtosecond determination of optical nonlinearities in CdS, GaP, ZaO, ZnS, ZnSe and ZnTe

Abstract

In this study, a femtosecond laser was employed to measure the nonlinear refractive coefficient induced by the bound electronic effect. Further, a single-color time-resolved Z-scan was performed to determine the relaxation of the nonlinear refraction contributed by bound-electrons and free-carriers, respectively. The obtained values show good agreement with other results and theoretical expectation.
