We report on large energy pulse generation in an erbium-doped
fiber laser passively mode-locked with atomic layer graphene. Stable mode
locked pulses with single pulse energy up to 7.3 nJ and pulse width of 415
fs have been directly generated from the laser. Our results show that atomic
layer graphene could be a promising saturable absorber for large energy
