Graphene-based passively mode-locked erbium doped fiber laser is presented. Multilayer graphene was obtained by mechanical exfoliation of pure graphitic block and deposited on the fiber ferrule. The mode-locking performance was investigated under various laser pumping conditions. The laser could operate at fundamental repetition rate of 16.34 MHz with 844 fs pulse duration and 30 mW average output power. Also harmonic-mode locking of the laser is demonstrated. 294 and 800 MHz repetition rates were obtained (corresponding to the 18th and 49th harmonic of the fundamental repetition frequency, respectively) with nearly transform-limited pulses.
