Self accelerating super Airy beam
In most applications of Airy beams, the primary focus is on the main lobe, since it has the highest field intensity. Therefore, the physical parameters such as the size and intensity of the main lobe play an important role to improve both the qualitative and quantitative information. Therefore, we introduce, theoretically and experimentally, the concept of a diffraction-free “super-Airy” beam, in which the main lobe is reduced to nearly half in size with increased intensity in comparison to the main lobe of the optical Airy beam,while maintaining the same transverse acceleration. It is also observed that when the super-Airy main lobe is blocked during propagation, it recovers to the original size faster than the Airy main lobe.
