Stimulated Scattering by Elastic Vibrations of Nanoparticles in an Optical Resonator with Nanodisperse Filling

Results are presented from studying the dynamics of dielectric nanoparticles and the electromagnetic field in an optical cavity filled with liquid and excited by external monochromatic radiation. The nonlinear polarization of the medium is determined and the stationary regime of nonlinear excitation of the electromagnetic field in the resonator is described. The buildup of elastic pulsations of particles under the action of ponderomotive forces in an electromagnetic field generates fields of combination frequencies.
