摘　　要：介绍了2.0μm波段掺铥连续单频光纤激光器的实验研究进展,以实现单频光纤激光器的关键技术为主线,总结了不同腔结构掺铥单频光纤激光振荡器的研究现状与发展方向。基于种子源主振荡功率放大(MOPA)结构进行了单频激光器功率放大,介绍了高功率掺铥单频光纤MOPA激光器的国内外研究进展。此外,介绍了本课题组在高掺杂铥锗酸盐玻璃光纤制作,2.0μm波段单频光纤激光振荡器构建,以及单频激光功率放大方面的部分研究工作。The experimental research progress of 2.0μm band Tin-doped continuous wave （CW） single-frequency fiber laser is introduced. With a focus on the key technologies in realizing the single-frequency fiber lasers, the present research status and development directions of the Tin-doped single frequency lasers with different cavities are summarized. Based on master-oscillator power amplifier （MOPA） of laser seeds, the power amplification of single-frequency lasers is realized and the research progress of high-power Tin-doped single frequency fiber MOPA lasers at home and abroad is summarized. In addition, some research works in our research group related to the fabrication of highly Tin-doped germanate glass fibers, the construction of 2.0 μm-band single frequency laser oscillators, and the power amplification of single-frequency lasers are presented.
