Abstract

Vortex optical field is widely used in optical communication, particle control, quantum information and other fields due to its special physical structure. Coherence is an important inherent property of the beam, with unique advantages in resistance to speckle noise and atmospheric turbulence disturbance. In this paper, taking the cosine-Gaussian correlation function as an typical example, a mathematical model of the cosine-Gaussian-correlated Schell model vortex (CGCSMV) source is established. Using the extended Huygens-Fresnel integral, and the generalized anisotropic turbulence spectral model, we derive an analytical expression for the far-field cross spectral density function of a CGCSMV beam propagating in anisotropic turbulence. Lastly, we perform numerical simulations of the behaviors of the far-field spectrum of our beam. The results of this paper have some practical reference value for the new optical field regulation, optical communication and lidar system.
