摘要

We report a simply designed gain-switched all-fiber laser emitting a maximum average output power of 11.2 W at 2.826 pm. The corresponding extracted pulse energy is 80 mu J at a pulse duration of 170 ns. These performances significantly surpass previous gain-switched demonstrations and are close to the state-of-the-art Q-switched laser performances near 2.8 pm, but with a much simpler and robust all-fiber design. The spliceless laser cavity is made of a heavily erbium-doped fluoride glass fiber and is bounded by fiber Bragg gratings written directly in the gain fiber through the protective polymer coating.
