Perfect vortex beam is a light field whose radial profile is independent of Orbital Angular Momentum (OAM). This new kind of optical vortex beams has unique advantages not only in the field of fiber coupling, optical trapping and tweezing but also in free space optical communication. This work provides a simulation method to analyze the mode purity evolution of perfect vortex beams in turbulent media, aiming to present an insight to the influence on the superposition types of multimode light fields. It is found that the anti-disturbance ability of multimode perfect vortex is better than that of single mode under certain conditions. Incoherent superposition leads to a stronger turbulence resistance and a more stable output compared to those of coherent superposition. The results of this paper can be useful in the fields of free space optical communication.
