Atomic multi-layer graphene film as a saturable absorber was first demonstrated to be able to mode lock Ytterbium-doped fiber lasers at wavelength around 1 um. Determined by the operation conditions, single or multiple dissipative solitons (DSs) can be generated in the fiber lasers. DSs with pulse duration of 550∼630 ps were generated. As graphene can also be used to mode lock erbium-doped fiber lasers at wavelength around 1.55 um, our result shows that graphene has indeed wavelength-independent saturable absorption, which could be exploited to mode lock fiber lasers with various operating wavelengths.
