Assessment of spatial coherence of a vortex axisymmetric Airy beam propagating in the turbulent atmosphere

摘要

For a vortex axisymmetric Airy beam, the second-order mutual coherence function for the complex amplitude of the wave field was calculated by two methods. The first method assumed previous calculation of the complex amplitude of wave field of the beam in a turbulent medium based on the Monte Carlo technique, while the second method used the well-known representation of the solution of equation for the second-order spatial coherence function. Coherent properties of the beam at different values of parameters are studied.
