Effects of Turbulence Instabilities on Laser Propagation

Abstract

Some remarks are presented on Furutsu's recent theoretical analysis of irradiance scintillation and the author defines and computes useful criteria for the resolution of point features on an illuminated target in turbulent air. The results are related to the work on focal-spot areas. The coefficient of the log-amplitude variance in the saturation regime is computed. Finally, the work on power spectra of angle-of-arrival fluctuations is expanded to include a simple interferometer. Two physical cases, simply related to the ray formulas, appear to apply in most practical situations.
