10 GHz fundamental mode fiber laser using a graphene saturable absorber

All-fiber mode-locked lasers with fundamental repetition rates of several gigahertz are sought after for applications in optical communications and metrology. In this paper, we propose a fiber Fabry-Pérot laser mode-locked by a graphene-based saturable absorber that operates at a fundamental repetition rate of 9.67 GHz. We use this laser as the seed for the generation of supercontinuum with 0.08 nm mode spacing.
