摘　　要：径向偏振光与传统的均匀偏振光相比,其偏振态具有完美的轴对称特性,而且其光强在中心轴上始终为中空的分布。对近年来国内外学者对径向偏振光的研究现状进行了综述,简要介绍了径向偏振光的电场特性、产生方法及其应用。通过分析总结认为,采用衍射光栅反射镜是产生高功率和高质量径向偏振激光的新的发展趋势之一。Compared with the traditional uniformly polarized light, the radially polarized laser performs perfect spatial axial symmetry and its light intensity configuration is always zero along the central axis. Based on reviewing recent work, its optical properties, generation methods and newest applications are summarized. In accordance with this methods, we summarize that using the diffraction grating mirror to generate radially polarized laser is the most valued method of generating high-quality and high-power radially polarized laser.
