Abstract :
A simple model, based on incoherent superpositions of suitably shifted and tilted lowest order Gaussian beams, is used to describe J 0-correlated partially coherent sources, whose intensity profile is Gaussian. Such a model also provides a generalization of the J0-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 M2 quality factor is also given, together with a possible experimental setup for the synthesis of such sources
