Non-diffracting super-airy beam with intensified main lobe

Abstract

We study, theoretically and experimentally, the concept of non-diffracting super-Airy beam, where the main lobe of the beam is observed to be nearly half in size and with increased intensity compared to the main lobe of the Airy beam. However, reducing the main lobe size does not affect the transverse acceleration and non-spreading features of the beam. Furthermore, we observed that during propagation, super Airy main lobe shows faster self-reconstruction after an obstruction than the Airy main lobe. Therefore, we envision that specifically, a beam with a smaller lobe size and higher intensity can out-perform the Airy beam for applications such as nonlinear optics, curved plasma generation, laser micromachining, and micro- particle manipulation, while the faster reconstruction property of the super-Airy main lobe can surpass the Airy beam in applications of scattering and turbulent media.
