| 摘 要： | 基于矢量瑞利-索末菲衍射积分,研究了矢量空心高斯光束横向光场和纵向光场在自由空间中的传输特性.研究结果表明,空心高斯光束的横向光场与纵向光场在传输过程中光强分布情况并不相同,横向光场的光强分布具有旋转对称性,并且保持空心特性的距离受光束阶数的影响,而纵向光场不再具有旋转对称性,并且在理想状态下纵向光场可以一直保持空心特...

| Abstract: | Based on vectorial Rayleigh-Sommerfield diffraction integral,the propagation properties of vectorial Hollow Gaussian beams(HGBs) on transverse and longitudinal fields are studied in free space.The results show that intensity distributions on transverse and longitudinal fields are quite different in propagation process of HGBs,while the longitudinal field is not cylindrical symmetry as transverse field,and it can always keep hollow property ideally.Longitudinal fields in near field can be used to combine rad... |
