Abstract
The asymptotic solutions for the first- and second-order statistical moments of the amplitude of a plane optical wave propagating in a turbulent atmosphe re are derived from Maxwell's equations. These solutions show that the irradi ance variance would diverge to infinity if the probability distribution were log-normal but that it would tend to unity if the distribution were normal. Therefore, the widely used hypothesis of log-normal probability dist ribution is incompatible with the experimental observation of the saturation of the irradiance variance. An order of magnitude estimate of the propagatio n distance characteristic of these asymptotic solutions indicates that they should apply in the saturation region.
