Four-Photon Light Scattering by Mechanical Vibrations of Cylindrical Particles in Liquid Suspensions

Resumo

The four-photon low-frequency light scattering by acoustic vibrations of elastic inclusions in a liquid heterogeneous medium has been investigated. General expressions are obtained for the amplitude of electromagnetic wave generated in the field of specified two-frequency (Raman) optical pumping under conditions of induced longitudinal acoustic vibrations of cylindrical inclusions. The total field radiated by the suspension at a frequency shifted with respect to the pump frequency has been analytically calculated.
