Abstract

In a recent paper the authors considered partially coherent, finite aperture optical beam propagation in free space and the turbulent atmosphere. Optical beam spread, lateral coherence length and the degree of coherence were investigated for a finite Gaussian beam. In this paper, similar formulations are used to examine the lateral coherence and the average on-axis intensity propagation. A unified model is developed for the mutual coherence of general partially coherent sources. Numerical results for representative physical quantities are plotted to illustrate the mixed effects of the source coherence, turbulence, optical wavelength, field range, and aperture size on the characteristics of the focused and the collimated optical beam.
