摘要：

A gain-switched Tm-doped double-clad silica fiber laser operating at a wavelength of approximately 2mum 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 1.064mum 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 1mus. The output wavelength becomes longer, and the slope efficiency increases with the increase in fiber length. (C) 2005 Optical Society of America.
