Abstract

Stimulated Brillouin scattering under cw pumping in the presence of low reflectivity feedback is shown to exhibit huge sustained or random bursts of quasi-periodic emission with an underlying weak chaotic behaviour imposed on a dc background. Theoretical analysis is in accord with these findings establishing the origin of this nonlinear dynamical behaviour to be purely deterministic and dependent on both Brillouin gain and nonlinear dispersion. No conditions have been found for stable steady state operation. © 1991.
