摘　　要：介绍几种基于传统轴棱锥和新型轴棱锥产生局域空心光束的新方法,并基于几何光学、波动光学和矩阵光学理论进行分析和模拟.研究表明:4种方法都可以获得高质量且尺寸可调的局域空心光束,也都利用了轴棱锥高转换效率、高损伤阈值的优点,但在元件集成及加工制造上各有优缺点.Several new techniques that based on traditional axicon and new axicon for generating bottle beam are introduced.By using geometrical optics,wave optics and matrix optics theory to analyze and simulate,we found that the four methods are all available for generating high quality and size adjustable bottle beam.And the advantages of axicon,such as high conversion efficiency and high damage threshold were all token of by these methods.Each method shows its advantages and disadvantages in element integration and manufacturing technique.
