Repositioning and steering laser beam power via coherent combination of multiple Airy beams

Appl Opt. 2013 Dec 10;52(35):8512-7. doi: 10.1364/AO.52.008512.

Abstract

We study numerically and experimentally laser coherent combination (LCC) with multiple one- or two-dimensional Airy beams. It is shown that the method of LCC using Airy beams leads to a higher combining efficiency and a better feature of propagation than that using conventional Gaussian beams. Based on such coherent Airy beams combination, we propose a laser steering approach that could achieve large-angle beam steering (over 0.6°) without the need of using any mechanical steering component.
