Paper Abstract

Optical induction and study of convection in a thin film of dye doped nematic liquid crystal is reported. The temperature transverse gradient provided by the Gaussian beam profile makes possible the induction of convective motions of different regime in the nematic phase. These motions give rise to very large and non-uniform nonlinear phase modulation of the light, thus producing a corresponding far field intensity redistribution. The study of this distribution may provide important information about the convection in thin film liquids.
