Abstract
Spatial coherence of optical fields determines the propagation property of a light beam. In this paper, we study the atmospheric turbulence effect on ultraviolet(UV) beams. The degree of coherence of the UV beam is modelled as a fractional multi-Gaussian correlated Schell function with rotational symmetry. Results show that the spectral density of the UV beam can retain its shape over 1 km in weak and moderate atmosphere turbulence. The beam spread and slow decay of spectral density distribution of the UV would be beneficial for non-line-of-sight UV communications.
