Abstract
A general criterion is proposed predicting the onset of chaotic behavior for parametric processes in a laser-produced plasma. The conditions when the transition to the stochastic regime occur are determined for various parametric instabilities excited when a high intensity laser interacts with a plasma. The complicated temporal structure observed in 3/2ω0, 2ω0, 1ω0, and fast electron emission in experiments using high-intensity (I≃1015–17 W/cm2), short (τ L ≃ 40–200 psec) Nd laser pulses is attributed to the reflection seeded SBS instability being driven into this regime.
