Effects of Turbulence Instabilities on Laser Propagation

Abstract

Three developments are reported briefly, (a) an extension of average focalspot areas under turbulent atmospheric conditions to non-zero elevation angles, (b) computation of the temporal power spectrum of angle-of-arrival fluctuations, and (c) development of a new formalism for the irradiance of a plane wave leading to log-normal statistics and promising a saturation effect for the irradiance (not yet computed).
