Abstract：

We　demonstrate　the　ultrafast　graphene　oxide　mode-locked　Er-doped　fiber　lasers.　The　lasers　can　operate　in　all　anomalous　dispersion　regime　and　normal　dispersion　regime　respectively　through　the　cavity　design.　When　the　laser　operates　in　the　all　anomalous　dispersion　regime,　the　traditional　soliton　pulse　trains　at　repetition　rate　of　61　MHz　are　generated.　The　measured　pulse　width　is　500　fs,　spectral　width　is　5.7　nm,　and　the　maximum　output　power　is　6　mW,　corresponding　to　single　pulse　energy　of　0.1　nJ.　In　the　normal　dispersion　regime,　dissipative　soliton　pulse　trains　at　repetition　rate　of　11.5　MHz　are　generated.　The　pulse　width　is　143　ps,　spectral　width　is　2.4　nm,　and　the　maximum　output　power　is　21　mW,　corresponding　to　single　pulse　energy　of　1.8　nJ.
