Instabilities of Nearly Degenerate Stimulated Brillouin Scattering

Abstract

Temporal instabilities in stimulated Brillouin scattering of two counter-propagating mutually detuned laser beams depend on the intensity of the beams, the length of the interaction region and the frequency detuning. The detuning increases the threshold of stability and shifts the oscillation frequency of the unstable perturbations at the threshold.
