Abstract

The effects of a turbulent atmosphere on the intensity distribution of an aberrated Rectangular Partially Coherent Flat-Topped (RPCFT) beam were studied. An analytical formula for the intensity distribution was derived. The effects of source parameters - such as correlation length, order of flatness, aberration coefficient and initial beam divergence - on the intensity were analyzed. Detailed analysis demonstrates that these parameters have an influence on beam propagation properties. The analyses are illustrated by numerical examples and graphs.
