Analysis of the Influence of Aberration Distortions on the Intensity Pattern of Gauss-Laguerre Modes

Determining the order of a vortex beam is an important problem in optics. One way is to insert an astigmatic distortion. However, other types of aberrations, such as coma, can also be useful in determining the topological charge of a vortex beam. The influence of the type and magnitude of aberrations on the distortion of the intensity pattern of vortex beams is investigated using Gauss-Laguerre modes of different orders.
