Circular beams were introduced as a very general solution to the paraxial wave equation carrying orbital angular momentum. Here, we study their properties by looking at their normalization and their expansion in terms of Laguerre–Gauss modes. We also study their far-field divergence and, for particular cases of the beam parameters, their possible experimental generation.

Abstract
Circular beams were introduced as a very general solution to the paraxial wave equation carrying orbital angular momentum. Here, we study their properties by looking at their normalization and their expansion in terms of Laguerre–Gauss modes. We also study their far-field divergence and, for particular cases of the beam parameters, their possible experimental generation.File in questo prodotto:
