| 摘 要： | 首次提出产生局域空心光束(Bottle beam)的另一类新型锥透镜模型.讨论了凹凸两种模型,分别是在传统轴棱锥的底部磨削和胶合圆台结构形成.研究结果表明平面波正入射新型凹锥透镜可产生单个Bottle beam,正入射新型凸锥透镜可形成具有周期性的Bottle beam.通过几何光学分析了产生Bottle beam的原理,计算了Bottle beam的相关参数.由衍射积分理论分析和模拟了新型锥透镜后的光强分布特性,所得分析结果与几何光学分析基本符合.

| 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. |
