Abstract

We propose a simple strategy to produce multiple longitudinal focal spots by adjusting the initial parameters of vector beam with non-uniformly correlated structure and chose electromagnetic Hermite non-uniformly correlated (EMHNUC) beams as typical examples to explore the multi-focusing characteristics of the beam propagation in turbulent atmosphere. Furthermore, we also demonstrated how to control the foci’s number, intensity, and position by adjusting the vector beam’s initial parameters. Finally, the influence of the turbulent atmosphere on the focal spot intensity was analyzed. These beams may prove helpful in longitudinal optical trapping and manipulation of multiple particles and transparent material cutting.
