title: Dissipative soliton resonance and reverse saturable absorption in graphene oxide mode-locked all-normal-dispersion Yb-doped fiber laser.
abstract: We observed dissipative soliton resonance phenomenon in a graphene oxide mode-locked Yb-doped fiber laser, which delivered square-shaped pulse of 0.52 ns~60.8 ns and single pulse energy of 159.4 nJ at 1064.9 nm. The 3 dB-bandwidth of Lorentz-shaped spectrum was 0.19 nm. We pointed out that the reverse saturable absorption played a big role in generating square-shaped or flat-top pulses, which verified by additional simulation work.
