Orbital angular momentum entangled states of vortex beam pump in non-Kolmogorov turbulence channel

The effects of non-Kolmogorov turbulence on orbital angular momentum entangled states generated by the parametric down-conversion of vortex beam pump and propagating in slant atmospheric channel are analyzed. Our results demonstrate that both the coincidence probability and signal photon detection probability decrease with the increase of channel zenith angle, topological charge, channel length and increase of non-Kolmogorov parameter α from 3 to 4.
