A　high　power　white　super-continuum　(SC)　fiber　laser　and　a　white　SC　beam　combiner　are　demonstrated.　The　white　SC　laser　structure　includes　a　passive　mode-locked　seed　fiber　laser,　master　power　amplifiers　and　the　SC　generation　system　which　uses　photonic　crystal　fiber　(PCF)　with　small　mode　area　as　the　high　nonlinear　medium.　In　this　experiment,　we　adopt　the　thermally　expanded　core　fibers　technique　to　fabricate　a　high　power　all　fiber　mode　field　adapter　(MFA)　which　is　used　to　couple　high　power　pump　pulses　into　the　PCF,　and　it　can　work　successfully　under　the　incident　pulse　power　of　98　W　with　the　transmission　efficiency　of　82%.　Meanwhile,　a　self-made　repetition　frequency　multiplier　(RFM)　is　utilized　to　adjust　the　repetition　frequency　(RF)　of　pulse　and　control　the　nonlinear　(NL)　effects　in　the　amplification　process.　Finally,　a　43　W　high　power　white　SC　fiber　laser　source　is　achieved,　with　spectrum　ranging　from　450　nm　to　1700　nm,　spectral　width　below　10dB　flatness　exceeding　1000　nm.　In　addition,　through　theoretical　simulation　and　designed　specially,　a　high　power　(7x1)　white　SC　combiner　is　obtained,　and　its　average　combining　efficiency　is　up　to　87.8%　with　the　testing　source　of　the　obtained　43　W　SC.
