Abstract

This paper analyzed the light induced lens response at the fiber optics scheme in transparent nanosuspension with electrostrictive nonlinearity. Ii was proposed the simple model of the phenomenon which can be used for describing the fiber optics experimental results in the nanosuspension. The received expression shows the monotonous growth (as the parabolic low) of the collected power versus the input power in ideal gas model of the nanoparticles ensemble. The thermal contribution due to Dufour effect is characterized by the negative sign and decreases the total response. The results are relevant to the study of the nonlinearity of the nanosuspension and optical diagnostics of such materials.
