Statistics of Two-Color Laser Beam Propagation in the Turbulent Atmosphere (Spectral Correlation)

摘要

Expressions were developed for the statistics of the angle-of-arrival fluctuations and of the irradiance fluctuations for a two-color laser beam after propagation through refractive turbulence in the atmosphere. The correlation, the cospectrum, and the coherence are included. The fluctuations in the angle-of-arrival and irradiance at two wavelengths were found to be highly correlated for most conditions of interest.
