Electrostriction parametric excitation of electromagnetic and elastic oscillations in oscillatory systems (resonators) is studied. The threshold powers and stationary amplitudes of parametric generation are determined in two modes: when the electromagnetic oscillations of the combination frequencies occur in the same mode of the resonator as the pumping oscillations and when the electromagnetic oscillations are converted into a different mode. Numerical calculations of the threshold power for KTaO/sub 3/ microwave resonators confirm the striction nature of the excitations observed in them.
