Paper Abstract

Much is said in the literature about Gaussian beams. However, there is little in terms of a quantitative comparison between the propagation of uniform and Gaussian beams. Even when results for both types of beams are given, they appear in a normalized form in such a way that some of the quantitative difference between them is lost. In this paper, we consider an aberration-free annular beam and investigate the effect of Gaussian amplitude across the aperture on the focal-plane irradiance and encircled-power distributions. We also consider the problem of aberration balancing and compare the effects of primary aberrations on the two types of beams.
