Description

The nonlinear dynamics of cw-pumped Brillouin long-fiber ring lasers that contain a large number of longitudinal modes N beneath the Brillouin gain curve is controlled by a single parameter, namely, the Stokes feedback R. Below R_crit , a stable train of dissipative solitonic pulses is spontaneously structured at the round-trip frequency f_r without any additional intracavity mode locking. Experimental observations in cw-pumped fiber ring cavities, supported by numerical simulation in a coherent space–time three-wave model that includes the optical Kerr effect, prove the universality of the self-pulsing mechanism. Stability analysis shows that below R_crit the steady Brillouin mirror regime is destabilized through a Hopf bifurcation. For R
