摘要：

This　paper　reports　an　all-fiber　super-continuum　(SC)　laser　source　with　the　output　of　307mw　in　average　power,　bandwidth　spanning　at　500nm∼1700nm　and　flatness　below　15dB.　The　SC　is　generated　in　PCF　(photonic　crystal　fiber)　which　is　pumped　by　a　mode-locked　picoseconds　fiber　laser,　while　taking　SESAM　(semiconductor　saturable　absorber　mirror)　as　mode-locked　device　and　FBG　(fiber　bragg　grating)　as　cavity　mirror　to　compose　the　resonator.　Through　optimizing　the　cavity　structure,　an　ultra-short　pulse　with　high　peak　power　is　achieved.　And　then　it　is　coupled　into　PCF　to　lead　to　the　super-continuum　because　of　a　series　of　nonlinear　effects.
