A General Algorithm for the Calculation of Laser Beam Spreading

Abstract

This paper compares two different beam spreading formalisms in the limits of near-and far-field, short exposure and long exposure. A description is given of an interpolation algorithm bridging the limits, giving entirely reasonable results in the intermediate regimes while having the proper limiting values.
