The basis of undesirable effect of parametric oscillatory instability in optical interferometer is provided by excitation of the additional (Stokes) optical mode having frequency Ω1, and the mirror elastic mode, having frequency Ωm. It appears when optical energy stored in the main mode, with frequency Ω0, exceeds a certain threshold and the frequencies are related as Ω0 Ω Ω1 + Ωm. We analyze time evolution of parametric instability which allows predicting the characteristics of precursors of parametric instability. Also we suggested device tranquilizer to dump the parametric instability. Observation of such precursors and the tranquilizer may help avoid parametric instability.
