We have experimentally investigated supercontinuum generated by using different pulse dynamics patterns as the
pump pulses. These patterns, which include conventional mode-locked single pulse, condensed phase pulses and
pulsed bunches, were all directly produced from a mode-locked erbium-doped fiber laser based on a multi-layer
graphene saturable absorber. The strong third-order optical nonlinearity of graphene and all fiber cavity
configuration led to the multi-pulses operation states at a low pump power. A flat supercontinuum with 20-dB width
of 550 nm from 1200 nm to 1750 nm have all been obtained by seeding the amplified conventional mode-locked
single pulse and condensed phase pulses into a segment of photonic crystal fiber. On the other hand, experimental
results also show that the pulsed bunches was not conducive to form a flat supercontinuum.
