Superposition Scheme for -Correlated Partially Coherent Sources

A simple model, based on incoherent superpositions of suitably shifted and tilted lowest order Gaussian beams, is used to describe -correlated partially coherent sources, whose intensity profile is Gaussian. Such a model also provides a generalization of the -correlated source and turns out to be effective in completely characterizing the propagation features of the radiated beam, such as its propagated optical intensity. The closed-form expression for the quality factor is also given, together with a possible experimental setup for the synthesis of such sources.
