We present an all-fiber passively mode-locked Raman laser using graphene as a saturable absorber. Different lengths of a highly non-linear fiber presenting normal dispersion at both pump and signal wavelengths are used in the cavity to provide Raman amplification. The cavity is pumped by a continuou...
