摘要：

In　this　article,　we　report　an　efficient　sub-nanosecond　pulses　generation　in　Yb-doped　fiber　laser　with　400　kHz　repetition　rate　and　960　ps　pulse　width,　which　adopts　master　oscillator　fiber　power　amplifier　(MOPA)　configuration,　extracting　8.9　W　average　output　power　up　to　23　kW　with　central　wavelength　of　1064.5　nm.　The　seed　laser　with　100　mW　average　output　power　is　amplified　to　8.9　W　by　one-stage　Yb-doped　double-cladding　fiber　amplifier,　pumped　by　6　multimode　laser　diodes　with　maximum　output　power　of　10　W.　This　kind　of　high-energy　sub-nanosecond　Yb-doped　fiber　laser　can　be　widely　used　in　material　processing,　laser　radar,　laser　ranging　and　other　fields.
