摘　　要：980nm波段掺镱光纤激光器在高亮度抽运源和蓝绿光源方面具有广泛的应用前景。首先介绍了980nm波段连续光纤激光器的研究价值、研究难点。然后,介绍了国内外研究机构在980nm波段连续光纤激光器和放大器方面的研究进展和存在的问题。最后对980nm波段连续光纤激光器和放大器未来发展方向进行探讨。Significance Yb-doped fiber lasers operating around 980 nm have attracted much attention because of their extensive application as high-brightness pumping sources.In addition,Yb-doped fiber lasers operating at this wavelength are potential sources for blue-green light.They can generate blue light around 488 nm for underwater communications and sensing by frequency doubling.However,it is challenging to achieve a high brightness with Yb-doped fiber lasers operating near 980 nm.The main reasons for this are that Yb-doped fiber lasers when operating near 980 nm not only have a high pumping threshold but also have serious gain competition with the amplified spontaneous emission(ASE)at around 1030 nm.A number of studies have been conducted on achieving high brightness with these lasers because of their wide application potential.The output power of continuous-wave(CW)Yb-doped fiber lasers operating near 980 nm was previously low,which limited their applicability.Researchers have enhanced their peak power by pulsing,realizing blue-green light output by frequency doubling.Although development of pulsed Yb-doped fiber lasers is advancing,people are still aiming to achieve a higher output power with CW fiber lasers.Early research progresses of CW Yb-doped fiber lasers operating near 980 nm have been reviewed in Ref.[16]and Ref.[17].However,these studies only review the research progress before 2011.In recent years,significant progress has been made with CW Yb-doped fiber lasers operating near 980 nm.In this study,the development of CW Yb-doped fiber lasers operating near 980 nm after 2011 is reviewed.The technical schemes and important experimental results are summarized and discussed.The future development of CW Yb-doped fiber lasers operating near 980 nm is also discussed.Progress In recent years,research outside China on CW Yb-doped fiber oscillators operating near 980 nm has involved optimization of the fiber design and significantly progressed fiberization of the fiber laser system.Thus far,an output power of 151 Wat
