Evolution of an Airy beam in turbulence

Abstract

The evolution of Airy beam intensity distribution in turbulence is examined. Results show that the centroid position and skewness of an Airy beam are independent on turbulence. When the exponential truncation factor is small, an Airy beam has a long tail on the left side. When the exponential truncation factor is larger than 1, an Airy beam can be approximately expressed by an off-axis Gaussian beam. If the effect of turbulence is large enough, the Airy beam converges to a Gaussian distribution. However, the convergence is slower for a small exponential truncation factor than for a large one. That is, an Airy beam with a smaller exponential truncation factor exhibits more resilience against perturbations of turbulence than does a larger one.

Reflection and refraction of an Airy beam at a dielectric interface

“…Another remarkable feature of Airy beams is their robustness against scattering or turbulent environments as well as their ability to self-heal and reproduce their wavefront even after they are severely perturbed or obstructed [10,11]. Other works have also shown the persistence of their features inside self-defocusing nonlinear media [12].…”

Simulation of Optical Signals Propagation in a Random Media

“…With the help of these methods propagation of optical signals from partially coherent source has been investigated [6,7], and also features of propagation of different laser beams in a turbulent medium have been studied, including Gaussian beams of higher orders [8], hollow beams [9], diffraction-free beams, such as Gauss-Bessel and Eerie beams [10,11], as well as cosine beams [12]. Wherein it was found that the higherorder Gaussian beams, including vortex bundles [13], as well as various spatially structured bundles become broader under the influence of turbulence in a lesser de-Information Technology and Nanotechnology (ITNT-2016) 56 gree than the fundamental Gaussian beam.…”

Changes of skewness and sharpness of partially coherent decentered annular beams on propagation

“…Several works were carried out concerning the sharpness changes of laser beams propagating in free space and through ABCD optical systems [2,3,[5][6][7]. But, vary a few of paper examined the skewness of a light beam [8].…”
