摘要:
利用柯林斯(Collins)积分方法, 导出了反常涡旋光束(Anomalous Vortex Beam,AVB)在梯度折射率(Gradient-index, GRIN)介质中的传输公式, 分析了AVB光束在GRIN介质中的传输特性, 讨论了光束参数和GRIN系数对传输特性的影响。研究表明, AVB光束在GRIN介质中传输时, 轴上光强分布及有效光束宽度随光束参数及介质折射率系数呈周期性变化, 在同一观察面上, 光束的暗核区域面积和最大光强随拓扑荷数m, 光束阶数n增加而增加。
Abstract:
By using Collins integral method, the analytical formula for anomalous vortex beams through the gradient-index media has been derived. The propagation properties of anomalous vortex beams in the gradient-index media have been analyzed. The effects of beam parameters and the gradient-index media parameters are discussed in detail. The research results show that the on-axis intensity distributions and the effective beam width of anomalous vortex beams varies periodically with the beam parameters and the gradient-index media parameters. The dark area and the maximum intensity of anomalous vortex beams increase with the increasing of topological charges m and beam orders n.
