Spectral Gaussian Schell-model beams

Abstract

A generalization of the classic Gaussian Schell-model source is considered for which the rms width of the beam $\sigma$ and the rms width of the spectral degree of coherence $\delta$ are assumed to depend on wavelength. It is shown that the functional form $\sigma (\lambda )$ and $\delta (\lambda )$ of such a source can affect the behavior of the spectral density, the degree of coherence, and the degree of polarization of the propagating beam.
