摘　　要：径向偏振光的横模表现为中空的环形分布,具有偏振方向始终沿着径向并与光轴成轴对称的特殊偏振形式。与空间均匀偏振光相比,径向偏振光在聚焦、粒子操控等方面更具优势,在工业加工、空间通信、显微技术等领域展现出巨大的应用价值。本文简要介绍了径向偏振光的电场特性,归纳总结了近十年径向偏振光产生方法的研究进展,简要阐述了这些产生方法所依据的原理,探讨了径向偏振光发展亟须解决的问题、可能的解决途径,并展望了径向偏振光相关研究的发展趋势。The transverse mode of a radially polarized beam has a hollow ring distribution,with a special polarization form along the polarization direction.Specifically,the polarization is always along the radial direction and is axisymmetric with the optical axis.Radially polarized beams,with better focusing and particle manipulation than spatially uniform polarized beams,have shown high application value in industrial processing,space communication,and microscopy.This study briefly introduces the electric field characteristics of radially polarized beams,summarizes the research progress and principles of generation methods for radially polarized beams in the last decade,discusses the problems that need to be solved for the further development of radially polarized beams and proposes possible solutions to these problems.Finally,it suggests the future development trend of radially polarized beamrelated research.
