Langevin’s model for soliton molecules in ultrafast fi ber ring laser cavity: investigating the interplay between noise and inertia

We describe the vibration pattern of a soliton-molecule using the Langevin’s model, i.e. noise source combined with a deterministic model. This simpler model allows investigating the interplay between fl uctuation and dissipation mechanisms at play.
