Spectrum of Partially Coherent Light: Transition from Near to Far Zone

摘要

The evolution of correlation-induced spectral shifts with propagation in freespace is investigated in the paraxial regime with particular emphasis on the transition from near to far zone. The dependence of spectral shifts on the state of coherence, the angle of observation, and the source linewidth is studied for partially coherent light generated by planar secondary gaussian Schell-model sources.
