Periodic bottle beam generated by novel axicon

Wu Zhiwei

Periodic bottle beam is a beam that has high practical value on scientific research. A novel axicon for generating periodic bottle beam was proposed. It was designed by grinding a conical surface whose dimension and conical angle were smaller than body in the middle of element bottom. The beam transformation property of this element was analyzed with geometrical optics theory, and the conclusion shows that its property is the same as the combination of two normal positive axicon with different conical angle. Besides, the relevant parameters were also calculated with geometrical optics theory. The intensity distribution was simulated by diffraction and interference theory. The results are basically consistent with the geometrical optics. The research shows that when a plane wave illuminates on the novel axicon, periodic bottle beam is formed.
