Abstract：

We　demonstrate　the　all-fiber　picosecond　erbium-doped　fiber　lasers　in　which　graphene　oxide　is　used　as　the　saturable　absorber.　The　linear　resonant　cavity　consists　of　a　narrow　band　fiber　Bragg　grating　and　a　graphene　oxide　saturable　absorber　mirror.　When　stable　mode-locked　pulses　of　the　fiber　laser　occur　at　22　mW　incident　pump　power,　the　pulse　repetition　rate　is　5.82　MHz　and　the　measured　pulse　width　is　87　ps.　The　spectral　central　wavelength　is　1549.3　nm,　the　3　dB　spectral　width　is　0.06　nm　and　the　signal-to-noise　ratio　is　66　dB.
