  • In order to study the spectral properties of J0-correlated partially coherent flat-topped beam in turbulent atmosphere,the analytical spectrum expression of J0-correlated partially coherent flat-topped beam was derived based on extended Huygens-Fresnel principle.The effect of structure constant,central frequency,spectrum width,coherence parameter and orders of flat-topped beams on the spectral shift was discussed.Results show that the above parameters have great effect on the value of the frequency shift.Furthermore,the spectral shift decreases with the increase of turbulence.In free space,the higher order of flat-top beam,the greater impact of the spectral shift,but the order has little effect on the spectral shift in turbulent atmosphere.
