Potential applications in nonlinear optical tweezing.

Abstract

The interactions between copropagating ring-Airy beams in a (2+1)-dimensional Kerr medium are numerically investigated for the first time. It is shown that two overlapping ring-Airy beams in such a medium produce controllable regions of very low intensity during propagation, the geometry of which can be manipulated by the tuning of initial beam parameters. This may prove useful for future optical tweezing applications in the nonlinear regime.
