摘要：

Based on a generalized truncated second-order irradiance moments definition, an analytical generalized beam propagation factor (M-G(2)-factor) of hard-edge diffracted cosh-Gaussian beams is derived and illustrated numerically. It is shown that the advantage of the method is its consistency with the previous results. The relevant subjects of truncated beams are also discussed. (C) 2000 Published by Elsevier Science B.V.
