Intensity and phase distribution of focused flattened Gaussian beams

We study the three-dimensional field distribution of a focused axially symmetric flattened Gaussian beam. As particular cases, we give the expressions of the intensity along the optical axis and at the focal plane. All our results are compared with those pertinent to the case of a converging spherical wave diffracted by a circular hole.
