Numerical simulations of sub-100 fs soliton fiber laser mode-locked by graphene

We demonstrate the generation of 98 fs soliton pulses in all-polarization maintaining fiber laser mode-locked by graphene saturable absorber. The experimental results are supported by detailed numerical simulations. We confirmed soliton-like pulse shaping in the cavity with strong dispersion-management. The developed computer model was used to study the intra-cavity pulse dynamics. These are the shortest soliton pulses generated in a fiber laser with graphene-based saturable absorber up to date (with the broadest optical spectrum).
