Kinetics of parametric instability of elastic waves in a dielectric
Parametric excitation of acoustic waves in a dielectric due to elastic nonlinearity of the medium is investigated. It was found that in the initial stage of excitation the phonon density increases exponentially with an instability increment which coincides with a known value from the parametric excitation theory.
