Abstract
A model for electromagnetic multi-Gaussian Schell-model beams is introduced. An analytical expression for the cross-spectral density matrix of electromagnetic multi-Gausssian Schell-model (EMGSM) beams propagating through non-Kolmogorov turbulence is derived based on the extended Huygens-Fresnel principle. With help of this expression, the average intensity, degree of coherence (DOC) and degree of polarization (DOP) of EMGSM beams are investigated in detail. Our results show that by suitable choices of the source parameters, the distance that preserve a flat profile can be prolonged. The effects of M and exponent value α on DOC and DOP of EMGSM beams are studied in detail.
