Paper Abstract

In this paper we consider the optimal coherence for beam propagation through random media. First, we demonstrate that a beam that maximizes the average receiver intensity is fully coherent, and that the upper bounds on received intensity are nearly attained by a beam that is focused for clear air. Second, we demonstrate that a beam that maximizes the scintillation index (along with other criteria that trade-off the mean and standard deviation for the received intensity) is, in general, partially coherent. We conclude with an example in which modal intensities are optimized for a beam that is constructed from Hermite-Gaussian modes.
