Thermodiffusion contribution in the thermal lens response of the nanosuspension

Abstract

A new two-beam configuration of the thermal lens method for the nonlinear optical diagnostics of nanosuspensions is presented. The proposed configuration eliminates the influence of the electrostrictive response and thus provides the determination of thermodiffusion coefficient of nanoparticles.
