Wideband tunable, graphene-mode locked, ultrafast laser
Abstract: We report a tunable ultrafast fiber laser mode-locked with a graphene saturable absorber. The linear dispersions of the Dirac electrons in graphene enable wideband tunability. We get ~1ps pulses, tunable between 1525 and 1559nm, demonstrating graphene as a broadband saturable absorber.
