摘要：

The　influences　of　central　wavelength　of　the　seed　pulse　and　gain　fiber　length　of　the　amplifier　on　the　characteristics　of　broadband　spectra　are　systematically　investigated　based　on　nonlinear　ytterbium-doped　fiber　amplifiers.　The　dissipative　solitons　from　the　nonlinear　amplifier　are　obtained　by　using　the　nonlinear　polarization　rotation　mode-locking　technique.　The　best　flat　wide　spectrum　with　wavelength　range　of　1040-1600　nm　is　obtained　when　the　center　wavelength　of　the　seed　pulse　is　1041　nm　and　the　gain　fiber　length　of　the　amplifier　is　8　m.　The　flatness　is　about　10　dB,　and　the　wide　spectral　flatness　is　less　than　1.5　dB　from　1040　to　1250　nm.　©　2019,　Chinese　Lasers　Press.　All　right　reserved.
