Abstract

The comparative analysis of the non-resonance mechanisms of cubic optical nonlinearity in aerosols was carried out. The analysis includes the thermal nonlinearity (thermal expansion of the materials) and the concentration nonlinearities caused by electrostriction and thermodiffusion effects as well as the reorientational cubic response. It is showed that the greatest values of nonlinear coefficient are provided by thermodiffusion and electrostrictive mechanisms of concentration nonlinearity. The results are relevant for nonlinear optics of aerosols, as well as optical diagnostics of such media.
