摘要：

Based　on　diode　laser　modulation　technique,　a　978　nm　nanosecond-pulsed　Yb-doped　fiber　laser　is　designed.　The　structure　of　the　laser　is　master　oscillator　power　amplifier.　The　laser　system　consists　of　the　seed　of　modulated　laser　diode　and　one　stage　Yb-doped　fiber　amplifier　with　single-mode　and　single-cladding.　The　spectral　central　wavelength　of　laser　diode　seed　is　set　as　978.3　nm　by　self-seeding.　The　laser　pulse　width　after　modulation　is　4.5　ns　and　the　repetition　frequency　is　tunable　at　10~50　MHz.　The　seed　light　is　amplified　to　115　mW　by　one　stage　Yb-doped　fiber　amplifier　with　single-cladding　when　the　repetition　frequency　of　laser　diode　seed　modulation　is　50　MHz.　The　corresponding　central　wavelength　of　the　laser　is　978.3　nm,　3　dB　spectral　bandwidth　is　0.11　nm.　The　obvious　amplified　spontaneous　emission　does　not　appear　in　the　spectrum　after　amplification.　©　2016,　Chinese　Lasers　Press.　All　right　reserved.
