摘要
随着光纤通信技术的发展，对于S波段（1450-1520nm）光放大的需求日渐升高，而Tm^＋3的能级结构中存在满足S波段光放大的能级跃迁，因此掺铥光纤放大器（TDFA）是S波段最具潜力的激光放大器件，对于光纤通信系统的通信窗口向S波段拓展具有十分重要的意义和价值．由于Tm^＋3的能级结构非常丰富并且拥有自身的特点，因此TDFA的泵浦波长有着众多的选择，其中一些泵浦方式拥有巨大的商业实用价值．
The demand of the S-band optical amplification is rapidly increasing with the development of optical communication technology, and the energy structure in Tm^＋3exists the transition which can meet the S-band, so thulium-doped fiber amplifier （TDFA） is the most important device for the S-band optical amplification, and its research will be very significant for the further broadening the optical communication bandwidth. The energy structure of the Tm^＋3is very complex and it has its own characteristics, so there are many options of pump wavelength for TDFA. And rome of those options have enormous commercial value.
