Propagation of Multiwavelength Laser Radiation through Atmospheric Turbulence
Abstract
The program represents a continuation of a comprehensive experimental investigation of laser beam scintillations due to atmospheric turbulence. The report summarizes the efforts that are underway on three aspects of the PROBLEM: (1) multiwavelength scintillations over a long horizontal path, (2) turbulence intermittency effects, and (3) transmitter-aperture effects including the cancellation of atmospherically-induced beam wander. The long-path horizontal measurements are expected to clarify the behavior of beam statistics at very high levels of integrated-path turbulence. The effects of fundamental turbulence intermittencies on data spread, confidence limits, and propagation analyses are postulated to be much more significant than generally realized. The cancellation of atmospherically-induced beam wander and the clarification of predictions from a recent theory of reciprocity for a turbulent path are of potentially great practical importance in the design of laser illumination systems.
