摘　　要：以泵浦效率的分析为视角和线索,综述了2μm掺Tm3+石英光纤激光器研究历史和最新进展。通过对交叉驰豫、能量传递上转换、激发态吸收及基态吸收等过程的考察,详细分析了掺Tm3+石英光纤激光器三个不同吸收带的泵浦跃迁机制。从斯托克斯效率、斜率效率及泵浦结构的角度比较了三个泵浦波带的效率和优劣。指出3H6→3H4跃迁泵浦与LD良好的光谱匹配使其成为掺Tm3+石英光纤激光器最理想的泵浦方案。The development of Tm^3＋ doped silica fiber lasers are introduced. Accon：ling to the absorbatien bands , pumping mechanisms of Tm^3＋ doped silica fiber laseas are categorized into three groups and analysied by accounting for CR, UC,ESA and GSD as well as the efficiency and advantages of them are compared from Stockes efficieney, slope efficiency and pumping structure perspectives. The results show that the ^3H6→^3H4 pumping is the most perfect one for the ideal spectrum overlap with LD.
