摘　　要：介绍近年来国内外对焦散光束的研究进展,分析基于光谱相位分类的两种基本焦散光束的自愈过程,以及唇状焦散光束和Pearcey焦散光束这两种典型光束的形成及传输特性,并对其应用前景进行展望.研究结果表明:相对于Bessel无衍射光束,焦散光束作为一种特殊的自愈合光束,在显微操控、拓扑电荷数检测和"吹雪机"等特殊领域具有其独特的优势.This paper introduces the research progress of caustic beams at home and abroad.The self-healing process of two basic caustic beams based on spectral phase classification is analyzed.The formation and transmission properties of two typical beams of lip-shaped caustic beam and Pearcey caustic beam are summarized in detail,and the prospect of their application is prospected.The results of the articles show that compared with the Bessel non-diffracting beam,the caustic beam is a special self-healing beam and has its unique advantages in special fields such as micromanipulation,topological charge detection and snow blower.
