Spectral shift of a Gaussian Schell-model beam beyond a thin lens

摘要

We give a comprehensive representation of the Wolf effect innpropagation both in free space and after a lens for an outstanding classnof partially coherent beams, namely Gaussian Schell-model beams. Wencharacterize the correlation-induced spectral changes, throughout thenwhole space, by means of isoshift lines and transverse shift profiles.nThe maximum value of the frequency blueshift, occurring on the opticalnaxis, is also calculated
