Gaussian Laser Beams via Oblate Spheroidal Waves
arXiv:physics/0312024
Abstract
We deduce a set of circularly polarized Gaussian laser beam modes via a separation-of-variables solution to the Helmholtz wave equation in oblate spheriodal coordinates. On transforming to cylindrical coordinates these become the well-known Gaussian-Laguerre modes.
