A gain-switched Tm-doped double-clad silica fiber laser operating at a wavelength of approximately 2µm with moderate output energy of 14.7mJ per pulse and a slope efficiency of 39.5% (with respect to launched pump energy) is realized pumped at 1.064µm from a Nd:YAG laser. The gain-switched fiber laser pulses are built up by a series of relaxation spikes, and every spike pulse duration is nearly 1µs. The output wavelength becomes longer, and the slope efficiency increases with the increase in fiber length.
