Average irradiance and polarization properties of a radially or azimuthally polarized beam in a turbulent atmosphere. Optics Express, 16(11), 7665-7673. http://dx.doi.org/10.1364/OE.16.0076651094-4087https://doi.org/10.1364/OE.16.007665https://hdl.handle.net/123456789/11171Analytical formulas are derived for the average irradiance and the degree of polarization of a radially or azimuthally polarized doughnut beam (PDB) propagating in a turbulent atmosphere by adopting a beam coherence-polarization matrix. It is found that the radial or azimuthal polarization structure of a radially or azimuthally PDB will be destroyed (i.e., a radially or azimuthally PDB is depolarized and becomes a partially polarized beam) and the doughnut beam spot becomes a circularly Gaussian beam spot during propagation in a turbulent atmosphere. The propagation properties are closely related to the parameters of the beam and the structure constant of the atmospheric turbulence.
