Observation of dissipative superluminous solitons in a Brillouin fiber ring laser

Abstract
Nonstationary stimulated Brillouin backscattering in a large gain optical-fiber ring cavity laser exhibits superluminous Stokes pulses of quasisoliton type and partial self-induced transparency for the pump. Experimental evidences, comforted by numerical simulation of the three-wave coherent model taking the acoustic-wave dynamics into account, show that this class of long transients occurs even with a cw-coupled pump wave.
