摘要：

A　passively　Q-switched　mode-locked　fiber　laser　based　on　graphene　saturable　absorber　mirror　is　reported.　A　large-mode-area　double-cladding　Yb-doped　photonic　crystal　fiber　is　adopted　as　a　gain　medium　and　a　linear　cavity　is　used.　At　pump　power　of　12　W,　the　maximum　output　power　of　115　mW　is　obtained　and　the　spectrum　is　centered　at　1039　nm　with　full　width　of　half　maximum　of　6　nm.　The　experimental　results　and　the　phenomenon　are　discussed　and　analyzed.
