  • Based on the Huygens-Fresnel principle,propagation equation for the spectral degree of coherence of partially coherent flat-topped beams propagating in a free space was derived,and the properties of the spectral degree of coherence were investigated numerically.The research shows that the oscillatory behavior and phase singularities of the spectral degree of coherence may occur.The oscillatory behavior becomes weaker and pairs of points with the phase singularities become fewer with the decreases of beam spatial correlation length and beam order,but the oscillatory behavior becomes stronger and pairs of points with the phase singularities become more with the increase of propagation distance.The width of the spectral degree of coherence becomes larger with the increase of propagation distance,i.e.,the spatial correlation of partially coherent flat-topped beams is improved with the increase of propagation distance.In addition,the relationship between the width of the spectral degree of coherence and the width of intensity is independent of the beam order and propagation distance,but only depends on the spatial correlation length.
