The analytical expressions for the cross-spectral density matrix elements of the partially
coherent elegant Laguerre–Gaussian (eLG) vortex beam propagating through anisotropic
turbulent plasma were derived based on the extended Huygens-Fresnel principle and used
to study the changes in the polarization degree and the coherence degree of the partially
coherent eLG vortex beam in the turbulent plasma. The numerical results show that the
polarization degree of a partially coherent eLG vortex beam reaches a specific value (which …
