Paper Abstract

The basis of undesirable e.ect of parametric oscillatory instability in Fabry-Perot cavity is 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 ω1 approximately equal to ω0 - ωm. The presence of anti-Stokes with frequency ω2 approximately equal to ω0 + ωm may depress parametric instability. We analyze the time evolution of parametric instability with account of both Stokes and anti-Stokes mode. It allows predicting the characteristics of precursors of parametric instability. Observation of such precursors may help to avoid parametric instability.
