A graphene-based Q-switcher is fabricated by the optical deposition of graphene in a fiber ferrule. The passively Q-switched Er-doped fiber ring laser with the Q-switcher as saturable absorber is made, which produces stable Q-switched pulse with pulse width of 8 s and maximum output average power 162.3 W. The repetition rate can be tuned from 5.1 kHz to 14.2 kHz with the increase of the pump power. The central wavelength can be tuned from 1556 nm to 1558 nm by rotating the polarization controller.
