Abstract
A purely analytical extension of flattened Gaussian beams [Opt. Commun. 107, 335 (1994)] to any values of beam order is here proposed. Due to it, the paraxial propagation problem of axially symmetric, coherent flat-top beams through arbitrary ABCD optical systems can definitely be solved in closed form via a particular bivariate confluent hypergeometric function.File in questo prodotto:
