Abstract
Specific features of the dynamics of reflection of optical beams in media with defocusing thermal nonlinearity have been studied. It is shown that, upon laser heating of a medium, the induced inhomogeneity profile outside the pump beam is determined by thermodiffusion and heat sink conditions at sidewalls. Signal-wave trajectory equations in a medium with an induced refractive index gradient have been derived and solved. A dependence of the nonlinear total internal reflection angle on the pump power and the initial distance between the beams has been established.
