Deterministic dynamical features have been experimentally observed in SBS with feedback, the latter seemingly acting to suppress stochasticity in the emission. However, such underlying deterministic behaviour is most readily interrogated in amplifier configuration in which effects of noise interaction can be eliminated. The significant findings in our analysis of such a system show that over-broad range of operating conditions the amplified signal exhibits deterministic chaos and instabilities as a consequence of the effects of nonlinear refraction and detuning. Without nonlinear refraction the amplified signal of the cw SBS seed is dominantly stochastic and cw amplification only occurs over a narrow range around the gain center.
