On z-coherence of beams radiated by Schell-model sources with Gaussian profile
On z-coherence of beams radiated by Schell-model sources with Gaussian profile
The degree of coherence and the intensity distribution on the axis of the beam radiated by a planar partially coherent source of the Schell-model type are investigated. We present an expression for the on-axis cross-spectral density which is valid for a very general Schell-model source, with the only constraint that …
