An alternative theoretical model named partially coherent hollow elliptical Gaussian beam (HEGB) is proposed to describe a partially coherent beam with an elliptical dark hollow profile Explicit expression for the propagation factors of a partially coherent HEGB is derived Based on the generalized Collins formula analytical formulae for the cross-spectral density and mean-squared beam width of a partially coherent HEGB propa
