Paper Abstract

We present a new pump-probe laser beams configuration of the thermal lens method for the nonlinear optical diagnostics of nanosuspensions. Trial-beam scheme eliminates the influence of the electrostrictive and light pressure effects and thus provides the more precise determination of thermodiffusion coefficient of nanoparticles. A mathematical model has been introduced to describe the thermo- and mass transfer in a nanofluid in a dual-pump beam field. The results are relevant to the study of the radiation self-action in the nanosuspension and optical diagnostics of such materials.
