Abstract
We observe the occurrence of several longitudinal modes in a stimulated Brillouin backscattering fiber ring laser operating in the unstable transition region between the stable cw and pulsed quasi-solitonic regimes. High order modes are preferentially excited, indicating a coupling between the two Brillouin processes in fibers, SBS and the guided-acoustic-wave Brillouin scattering (GAWBS).
