Abstract：

We　report　70　ns　pulse　generation　at　1064.2　nm　from　an　Yb-doped　fiber　laser　passively　Q-switched　by　a　graphene　saturable　absorber　in　a　short　linear　cavity.　The　maximum　output　power　was　12　mW　and　single　pulse　energy　was　46　nJ.　The　pulse　repetition　rate　of　the　laser　can　be　widely　tuned　from　140　kHz　to　257　kHz　along　with　the　increase　of　the　pump　power.　©　2011　IEEE.
