Abstract
Gaussian beam modes, which are normally associated with laser cavities and quasi-optical propagation, can be used to solve some classic problems in Fresnel diffraction. A particular advantage of the technique is that, for the cases of the uniformly illuminated circular aperture, narrow slit and straight edge, it is possible to derive analytical recursive relationships for the mode amplitude coefficients, which allow for speedy computation of the diffraction patterns.Keywords
