Self-Focusing Characteristics of Circular Array Airy Vortex Beams
A kind of circular array Airy vortex beam (CAAVB) is theoretically proposed and experimentally generated, which consists of multiple Airy beams arranged in an annular array and has the self-focusing performance. By increasing the number of Airy beam arrays, the self-focusing intensity can be effectively increased. The simulation results show that under the same conditions, the self-focusing characteristics of a CAAVB can be greatly improved by loading an optical vortex. In addition, by adjusting the radius of the annular airy beam array, the focusing position of the beam can be controlled and the non-mechanical adjustment of focus distance can be realized.
