. We have dynamically described and experimentally obtained the generation of stable trains of dissipative Brillouin solitons in fiber ring lasers below a critical feedback, 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 10 < L(m)/λ
