Paper Abstract

A mode-locked Er-doped fiber laser using graphene-covered-microfiber (GCMF) as saturable absorber is demonstrated. The GCMF has excellent interaction between the propagating light and graphene film via its large evanescent field. By improving the side-pump power and adjusting the PC, we successfully achieved pulse trains with a repetition rate of 1.7 MHz, which matches well with the length of the cavity. The pulse width was 380 fs. By tuning pump power and polarization states in the laser cavity, stable Q-switching, Q-switched mode-locking and continuous-wave mode-locking can be achieved in our experiments.
