Stationary Field Oscillations in an Optical Resonator with a Nanodisperse Filling under Monochromatic Excitation

Consideration is given to the stationary mode of electromagnetic field oscillations in a resonator filled with a nanodisperse liquid suspension and excited by an external monochromatic wave. A general case of excitation of field oscillations in a resonator at an arbitrary ratio between the field and thermal energies of nanoparticles is investigated. It is shown that the increase in the field intensity in the resonator is nonlinear due to spatial redistribution of impurity dielectric particles and that the increase in the pump intensity may allow changing the resonator transmission and blocking radiation not associated with light absorption by the particles.
