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 ω_m. 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 - ω_m. The presence of anti-Stokes with frequency ω₂ approximately equal to ω₀ + ω_m 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.
