Fiber optics method for nanomaterials diagnostics

Abstract

This paper analyzed the light induced lens response at the fiber optics scheme in transparent nanosuspension with electrostrictive nonlinearity. The theoretical analysis of the light-induced mass transfer in the nanosuspension was carried out for large intensities of the Gaussian beam radiation, when the concentration change is comparable to the primary. The nonlinear lens in this mode is the exponential function of the incident light intensity. The results are relevant to the study of the radiation self-action in the nanosuspension and optical diagnostics of such materials.
