The nonlinear index of refraction and the two-photon absorption coefficient of CdS, ZnSe, and ZnS were measured using the Z-scan technique with 100-femtosecond pulses at 610 nm, 780 nm, and 1.27 μm. The results are in reasonable agreement with measurements made at similar wavelengths with longer pulses. A simple theoretical model accounts for the dispersion of the nonlinearities and confirms their electronic nature.
