摘要：

In　this　paper,　a　single-mode　980nm　Yb-doped　fiber　laser　was　studied　carefully　in　theory　and　experiment.　Based　on　the　theoretical　research,　we　chose　an　appropriate　fiber　length　of　36.5　cm.　In　the　experiment,　by　adopting　two　0　fiber　ends　as　cavity　mirrors,　the　Yb-doped　fiber　laser　generated　a　total　output　power　of　1.32　W　at　980　nm　with　the　slope　efficiency　of　75.3%.Through　frequency　doubling　with　BIBO　crystal,　a　total　output　power　of　15　mW　at　490.8　nm　was　obtained.　Simultaneously,　we　produced　a　980nm　Yb-doped　single-mode　pulse　fiber　laser　pumped　by　an　acousto-optics　Q-switched　Nd:YAG　laser.　The　pulse　fiber　laser　generated　a　total　average　power　of　100　mW　at　980　nm　when　the　laser　pulse　was　10　ns　at　repetition　frequency　of　16　kHz.　©　2009　SPIE.
