In order to study influence of atmospheric turbulence on the Rayleigh range of partially coherent cosh-Gaussian beams, analytical analysis and numerical simulation were carried out. It is found that the Rayleigh range increases with the increase of laser coherent beam intensity, Gaussian waist and the inner scale of atmospheric turbulence and decreases with the increase of atmospheric refractive index fluctuation intensity and laser wavelength. The results show that effect of the inner scale of atmospheric turbulence on the Rayleigh range is significant, but the influence of outer scale is weak. The Rayleigh range depends on air quality and laser properties.
