摘　　要：掺铥光纤激光器(Tm-Doped Fiber Laser,TDFL)具有结构紧凑、散热性能优良、光束质量好、非线性效应阈值高等优点,其量子转换效率在理论上可达200%。TDFL产生的1.7~2.1μm激光在多个领域具有广泛应用。简要介绍了Tm^(3+)离子的吸收谱和能级结构、TDFL三种泵浦方式的优缺点以及国内外高功率TDFL的研究进展,并就其未来发展给出了初步看法。Tm-doped Fiber Lasers （TDFL） have the advantages of compact structure, excellent cooling capacity, good beam quality and high non-linear effect threshold etc. Theoretically, its quantum con-version efficiency can be up to 200%. The laser generated by TDFLs at the wavelengths from 1.7μm to 2.1μm has wide applications in many fields. The absorption spectrum and level structure of Tm^3＋, the advantages and disadvantages of three different pumping methods and the research progress of high power TDFLs at home and abroad are presented in brief. Finally, the preliminary view on the future development of high power TDFLs is given.
