Título: Effective model for nonlinear refraction and extinction coefficients in the presence of stimulated light scattering

Resumo: In this presentation we discuss a wave-coupled model to describe the effective nonlinear (NL) optical response of transparent materials illuminated by strong light beams in conditions such that stimulated light scattering is relevant. At sufficiently high intensities the NL light scattering will lead to non-perturbative effective NL refraction and NL absorption coefficients which can be misinterpreted as higher-order ultrafast NL polarization responses. As an application of the model we show that the existing divergent interpretations of carbon disulfide NL response in the picosecond and femtosecond regimes by several authors can be clarified in the framework of the wave-coupled model.
