Abstract: | The intensity distribution of the J0-correlated Schell-model (JSM) vortex beams focused by a lens and propagation in weak-to-strong turbulent atmosphere are investigated. It is shown that the beam spreading increases with the increase in topological charge n, the source coherent length α−1, turbulent outer scale L0 and propagation distance z. The center hollow depth of intensity distribution of the J0-correlated Schell-model (JSM) vortex beams decrease with the increase of topological charge n, turbulent outer scale L0 and propagation distance z or the decrease of the source coherent length α−1. |
