TLDR
In this article, the nonlinear index of refraction and the two-photon absorption coefficient of CdS, ZnSe, and ZnS were measured using the Zscan technique with 100 femtosecond pulses at 610 nm, 780 nm, and 1.27 μm.Abstract:
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.read more

Dispersion and band-gap scaling of the electronic Kerr effect in solids associated with two-photon absorption.
TL;DR: By using the two-photon-absorption spectrum as predicted by a two-parabolic-band model, this work can predict the observed universal dispersion, scaling, and values of ${\mathit{n}}_{2}$ that range over 4 orders of magnitude and change sign, using a simple Kramers-Kronig analysis.
