| 摘 要： | 研究了双曲余弦高斯涡旋光束不同振幅参量对光场分布的影响。在相同光涡旋的情况下改变振幅的大小,在焦平面上场强分布变化明显。涡旋光束的拓扑数对光束的聚焦特性存在明显影响,不同的拓扑数会引起聚焦区域光强分布变化,另外也产生一些新的多焦点阵列和多重菱形聚焦图案。

| Abstract: | Optical intensity distributions in the focal region play an important role in many optical systems. In this paper, the focal patterns of hyperbolic-cosh-Gaussian (HCG) beam in focal plane were investigated by changing amplitude. It was found that the focal patterns can be altered very considerably by changing the charge number of the amplitude,and some novel focal patterns appear, including multiple rhombus and multiple focal spots arry. |
