新型锥透镜产生局域空心光束
Bottle beam generated by novel axicon
摘要
Abstract
Novel axicon for generating bottle beam is proposed for the first time. We discuss concave and convex types, which are formed by grinding and scuffing a frustum of a cone on the bottom of a traditional axicon. The results show that when a plane wave illuminates on the concave axicon, a single bottle beam is formed. If the light illuminates on the convex axicon, periodic bottle beam is formed. The formation mechanism of the bottle beam is analyzed by geometrical optics, and the relevant parameters are also calculated. The transverse and the longitudinal intensity distribution are simulated by diffraction and interference theory. The results are basically consistent with the geometrical optics.关键词
