As the widely studied two-dimensional materials,MXenes are potential candidates for various nonlinear optical modulators due to their excellent properties,such as the ultrafast carrier dynamics,high optical damage thr...
We demonstrate that the intrinsic properties of monolayer graphene allow it to act as a more effective saturable absorber for mode-locking fiber lasers when compared to multilayer graphene. The absorption of monolayer...

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...
