Abstract

The question of laser beam propagation in a disturbed atmosphere has been considered. In this paper an overview is presented of the sensitivity of beam propagation to turbulence in the neutral atmosphere. Using the lateral coherence length as a measure of beam modification, the variation of the coherence length is considered as a function of a variety of fluid parameters that characterize the disturbed and turbulent atmosphere. It was found that subsonic turbulence occurring with densities representative of the ambient atmosphere at 80 km could produce significant effects on the propagation of a laser beam.
