The corresponding extracted pulse energy is 80\&\#x00A0;\&\#x00B5;J at a pulse duration of 170\&\#x00A0;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\&\#x00A0;\&\#x00B5;m, 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.}, }
