Abstract

General anisotropy leads to different effects along the horizontal axis of a propagating beam than along the vertical axis. To better understand these effects, we developed theoretical models for beam diameter, mean intensity, and scintillation index of a Gaussian-beam wave. Two methods, valid in both weak and strong fluctuation regimes, are compared to determine beam diameter. Scintillation-index contours exhibit an elliptical shape corresponding to anisotropy while mean-intensity contours vary with path length and have no such obvious correspondence. The mean-intensity and scintillation-index analyses are based on weak-irradiance-fluctuation theory.
