| 摘 要： | 利用几何光学的光学追迹法，对梯度轴棱锥系统产生周期性局域空心光束（bottle beam）的演变过程进行描述。利用光学仿真软件的光照度分析功能，对光束传播中不同传播距离的截面光强分布进行了模拟。结果表明，通过改变两个轴棱锥底角大小，可以对周期性局域空心区域的长度进行控制。这种梯度轴棱锥系统可以很容易地产生尺寸非常小的周...

| Abstract: | The evolution of the periodic bottle beam generated by a gradient axicon system is described by a novel method based on the ray-tracing.The transverse intensity distributions of the Bottle beam in propagation are simulated by using the irradiance map function of optical simulation software.It is shown that the region of generating the periodic bottle beam can be controlled by changing the two cone angles of the axicon.The small-size bottle beam can be generated by using the gradient axicon syste... |
