Abstract: | The degree of polarization is found for optical excitations of cosh-Gaussian, cos-Gaussian and annular-Gaussian beams in a
turbulent atmosphere. The related formulation is based on the beam coherence polarization matrix. The self and mutual coherence
functions appearing in the beam coherence polarization matrix are evaluated, when the above mentioned excitations exhibit
partial source coherence for self and cross fields. Plots showing the variation of the degree of polarization are provided
versus the propagation length when the source size, displacement parameter, structure constant and the degree of source coherence
for self and cross fields change.
