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.
摘要
圆形光束作为携带轨道角动量的傍轴波动方程的一种非常通用的解被引入。在此，我们通过研究其归一化以及用拉盖尔 - 高斯模式展开来研究它们的性质。我们还研究了它们的远场发散，并且对于光束参数的特定情况，研究了它们可能的实验产生方式。
