Abstract

We discuss the use of the truncated second-order moment as an appropriate way of getting rid of the troublesome divergence problem caused by hard-edge diffraction. This approach preserves the simplicity of the propagation law of the beam size and makes the beam-propagation factor nearly invariant when propagation in ABCD systems is considered.
