Abstract
Nonlinear optical techniques are widely used for the optical diagnostics of materials. The thermo-induced pseudo-prism method is used to study of the two-component materials. It is measured the angle of the light beam in the material with the thermo-induced refractive index gradient. This paper proposes a way to create pseudo-prisms in the nanodispersive liquid through the light radiation pressure. In the dispersed environment there is a specific mechanism of optical nonlinearity based on the redistribution of the dispersed particle concentration in the light field. The theoretical analysis of the light induced mass transport task was executed in the dispersed medium in a homogeneous light field. As a result of the analytical solution of the light induced mass transport task it was obtained an expression for the deflection angle of the beam in a pseudo-prism. The results are relevant in the study of the dispersed liquid media, as well as optical diagnostics of such materials.
