提出一种用环形光束产生局域空心光的新方法，即用环形光束垂直入射锥透镜底面，沿光轴方向就会产生局域空心光。用几何光学分析模拟了环形光束产生的局域空心光的过程和传输方向上不同位置的截面光强分布，推导了局域空心光暗域的横向和径向大小的计算式，分析了影响局域空心光暗域的大小的因素，并给出相关的实验结果，实验与理论基本吻合。与双锥透镜、锥透镜透镜产生局域空心光相比，这种方法结构简单，元件容易加工，具有重要的应用价值。

A new way to generate bottle beam by using annular beam is presented. When annular beam illuminates perpendicularly bottom surface of axicon, bottle beam is generated along the optical axis behind the axicon. Process of generating bottle beam and transverse intensity distribution at different location on optical axis are analyzed by using geometrical optics. Formulas for calculate bottle beam sizes are deduced and the factors affecting bottle beam sizes are discussed. The results of contrast experiment agree approximately with theoretical analysis. Compared with doubleaxicon and axiconlens, this method for generating bottle beam is simple in operation and the optical elements processing is easy, so it is important in applications.
