We report our recent experimental observation and theoretical analysis of nonlinear dynamics in stimulated Brillouin scattering (SBS) generated in single mode fibre in the presence of weak external feedback. Both experiment and theory establish that the noise, which initiates this process and dominates the emission near the SBS threshold, is dramatically suppressed from the onset of SBS emission, giving rise to various highly deterministic dynamical features. Further in this analysis we identify the critical role of nonlinear refraction on the nonlinear dynamical behaviour. © 1995.
