    Abstract

    Based on the theory of generalized Huygens theory and the unified theory of coherence and polarization, distribution of the intensity of partially coherent radially polarized beams influenced by source wavelength, and degree of polarization (DOP) influenced by coherence, atmosphere turbulence intensity, spot size and source wavelength, are investigated while propagating in turbulent atmosphere. It is shown that while the partially coherent radially polarized beams propagate in turbulent atmosphere, the distribution of intensity is affected by source wavelength obviously. With the increase of propagation distance, the doughnut beam spot of the partially coherent radially polarized beam becomes a solid beam, which is related to source wavelength. The shorter the source wavelength is, the longer distance the partially coherent radially polarized beam propagates to form a solid beam shape. In addition, distribution of DOP is also affected by coherence, atmosphere turbulence intensity, spot size and source wavelength. At a certain propagation distance, the rate of DOP with radius increases with the larger original coherence, the weaker atmosphere turbulence intensity, the bigger spot size and the shorter source wavelength. Such tendency becomes more obvious with longer propagation distance.
