A stable, wideband tunable, near transform-limited, graphene-mode-locked, ultrafast laser
Graphene, saturable absorber, mode-locking, fiber laser
We report an ultrafast laser mode-locked with a graphene saturable absorber. The linear dispersions of the Dirac electrons in graphene enable wideband tunability. We get ~1 ps pulses, tunable between 1525 and 1559 nm, with stable mode-locking, insensitive to environmental perturbations.
