Theory of Propagation of Partially Coherent Light Beams in a Turbulent Atmosphere

Abstract

The function of mutual coherence is considered for a partially coherent light source in a turbulent medium. The behaviour of the effective radius of the coherence peff determining the angular beamwidth is investigated. The dependence of the mean light intensity in the turbulent medium on the initial beam coherence is also considered. It is shown that the mean intensities for coherent and incoherent sources become close at a sufficiently strong level of turbulence.
