Super-continuum　(SC)　is　widely　used　in　coherent　photography　technology,　optical　spectroscopy　analysis,　interferometry,　etc　because　of　its　flat　and　broad　spectrum,　high　spatial　coherence　and　high　power.　Super-continuum　generation　could　be　realized　on　theory　by　ultra-short　pulse　laser　getting　through　the　high　nonlinear　medium,　accompany　with　self-phase　modulation　(SPM),　stimulated　Raman　scattering　(SRS),　four-wave　mixing　(FWM).　With　the　development　of　fiber　technology,　Yb-doped　ultra-short　pulse　fiber　laser,　which　has　high　peak　power,　high　optic-to-optic　efficiency,　compact　structure　and　small　volume　was　elected　as　the　pump　source,　and　high　nonlinear　photonic　crystal　fiber　(PCF)　as　the　nonlinear　medium　for　SC.　In　this　paper,　a　self-made　amplified　mode-locked　pulse　was　coupled　into　a　10m　PCF,　with　1　040　nm　zero　dispersion　point,　to　generate　8.13W　super-continuum　by　fusing　method,　during　which　the　key　parameters　like　discharge　time,　discharge　interval,　splice　loss　are　seriously　optimized　to　keep　the　fusing　quality　well.　©,　2014,　Chinese　Society　of　Astronautics.　All　right　reserved.
