An　all-fiber　high　power,　blue-enhanced　supercontinuum　generation　in　a　piece　of　uniform　photonic　crystal　fiber　pumped　by　a　picosecond　Yb-doped　master　oscillator　power　amplifier　(MOPA)　is　experimentally　demonstrated.　The　MOPA　source　is　seeded　by　an　actively　dissipative　soliton　mode-locked　Yb-doped　fiber　laser　with　a　fundamental　repetition　rate　of　approximately　15.33　MHz　and　a　large　chirp.　By　introducing　giant　chirp　to　the　seed　pulses　and　optimizing　the　pump　power　in　every　stage　of　the　MOPA,　an　SC　with　30.6-W　output　average　power　and　an　extremely　wide　spectrum　of　385　nm　to　beyond　2400　nm　is　obtained.
