Abstract

We comment on a recent paper by Seshadri [Appl. Opt. 45, 5335 (2006)]. In the cited work the author utilized the so-named Felsen method in order to derive the full wave expression of a scalar Bessel–Gauss field, propagating in free space, originated from an assigned input distribution on the source plane $z=0$. As we show, the author’s obtained results do not correctly reproduce the aforesaid input field distribution, as, on the contrary, they have to do.
