Q-switched operation of an erbium-doped fiber laser with fiber grating mirrors is demonstrated for the first time. The resonator was formed by splicing two fiber gratings to erbium-doped fiber ends. One of the fiber gratings was periodically stretched by a piezoelectric transducer for the Q-switching operation. An output pulse with a pulse width of 2.46 μs and a peak power of 2.1mW was obtained for a 1.48 μm pump power of 26 mW. The oscillation wavelength was 1.552 μm and the repetition rate was 1 kHz. The laser oscillation wavelength was tuned from 1.552 μm. to 1.556 μm by applying lateral stress to one of the fiber grating mirrors.
