Abstract：

The　graphene-oxide-based　passively　Q-switched　erbium-doped　fiber　laser　is　first　reported.　The　laser　adopts　ring　cavity　configuration,　and　the　Q-switcher　is　the　self-made　graphene　oxide　saturable　absorber　mirror.　Stable　Q-switched　pulses　with　the　frequency　of　68~124　kHz　and　pulse　width　of　0.47~1.6　μs　are　output　at　80~505　mW　incident　pump　power.　Limited　by　the　pump　power,　the　maximum　output　power　is　10　mW,　corresponding　to　the　single　pulse　energy　of　80.6　nJ.　This　kind　of　new　Q-switched　fiber　laser　with　graphene　oxide　as　the　saturable　absorber　will　have　great　applications,　due　to　its　advantages　of　low　price,　simple　design　and　high　stability.
