| Abstract: | 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. |
