Abstract :
Gabor´s expansion of an aperture field in a discrete two-dimensional superposition of Gaussian elementary beams is extended to incorporate exponential beams. The resultant expansion scheme has an advantage over the commonly used Gaussian beam representation in situations involving an exponential aperture distribution such as the modal field in a thin slab laser amplifier
