Abstract
Stimulated Brillouin scattering (SBS) of a cw-pump Ep in an optical fiber is able to generate a counterpropagating Stokes pulse EB by resonant interaction with high frequency (GHz) axial acoustic waves Ea. We have dynamically described and experimentally obtained the generation of stable trains of dissipative Brillouin solitons in fiber ring lasers below a critical feedback [1], when the cavities contain a large number of longitudinal modes N beneath the Brillouin gain curve. Stable self-pulsed regimes of nanosecond Brillouin solitons are obtained in a finite range of fiber length [namely ], their Fourier transform spectra showing only a few number of cavity modes coupled together.
