Electrostriction mechanism of light induced lens response in nanosuspension

Abstract

A theoretical analysis of the light induced mass transfer in a dispersive liquid is carried out for large intensities of radiation in the field of Gaussian beam. The non-linear lens exponentially increases with the intensity of light, when the change in concentration is greater or comparable to the primary value. It is shown that the light induced response is limited by the Raleigh scattering for the case of high concentrations of nanoparticles.
