Non-paraxial Airy beams

TL;DR

This paper investigates the behavior of Airy light beams under non-paraxial conditions, analyzing how their propagation and structure change as the paraxiality parameter varies, with a focus on evanescent wave contributions.

Contribution

It introduces a general Fourier-based approach to study non-paraxial Airy beams and explores the transformation of their form and the role of evanescent waves in this regime.

Findings

Beam transforms from Airy form as paraxiality decreases

Evanescent waves significantly influence non-paraxial propagation

The approach provides insights into non-paraxial beam dynamics

Abstract

We report the propagation dynamics of Airy light beams under non-paraxial conditions. It is studied using the general approach which deals with Fourier expansion of the beam. We show the transformation of the beam from the Airy form as the paraxiality parameter decreases. The role of evanescent waves in non-paraxial regime is discussed.
