“…More exotic possibilities involve the use of so-called Bessel beams [47], which can be nondiffracting over large propagation distances, and Airy beams [48], which can exhibit transverse acceleration. Chen and Pu [49] have investigated Bessel beams in turbulence, while Chu [50] has studied Airy beams. Perhaps unsurprisingly, the turbulence always "wins" over sufficiently long distances, erasing the special features of the beam and reducing it to a Gaussian profile.…”

“…Arguments have been put forward for one mode family being more robust than another, with studies covering Bessel–Gaussian, 42 – 53 Hermite–Gaussian, 54 – 56 Laguerre–Gaussian (LG), 57 – 61 and Ince–Gaussian 62 beams, with mixed and contradictory results. In the context of OAM, since the atmosphere itself can be thought of giving or taking OAM from the beam, it has been shown theoretically and experimentally that atmospheric turbulence distortions are independent of the original OAM mode, 63 all susceptible to the deleterious effects of atmospheric turbulence, and indeed, it has been suggested that OAM is not the ideal modal carrier through turbulence 64 .…”

Robust structured light in atmospheric turbulence

Structured light is routinely used in free-space optical communication channels, both classical and quantum, where information is encoded in the spatial structure of the mode for increased bandwidth. Both real-world and experimentally simulated turbulence conditions have revealed that free-space structured light modes are perturbed in some manner by turbulence, resulting in both amplitude and phase distortions, and consequently, much attention has focused on whether one mode type is more robust than another, but with seemingly inconclusive and contradictory results. We present complex forms of structured light that are invariant under propagation through the atmosphere: the true eigenmodes of atmospheric turbulence. We provide a theoretical procedure for obtaining these eigenmodes and confirm their invariance both numerically and experimentally. Although we have demonstrated the approach on atmospheric turbulence, its generality allows it to be extended to other channels too, such as aberrated paths, underwater, and in optical fiber.

“…The BG beams can be generated by an axicon, a light modulator, or other elements [ 6 , 7 , 8 ]. Bessel–Gaussian beams are convenient for probing the turbulent atmosphere since, on one hand, they are of a finite energy like the Gaussian beam and, on the other hand, they manifest quasi-diffraction-free properties due to the Bessel function [ 9 , 10 , 11 , 12 ]. As was shown in [ 13 ], BG beams are more resistant to the distortions induced by a turbulent atmosphere than the Gaussian beam.…”

Double and Square Bessel–Gaussian Beams

We obtain a transform that relates the standard Bessel–Gaussian (BG) beams with BG beams described by the Bessel function of a half-integer order and quadratic radial dependence in the argument. We also study square vortex BG beams, described by the square of the Bessel function, and the products of two vortex BG beams (double-BG beams), described by a product of two different integer-order Bessel functions. To describe the propagation of these beams in free space, we derive expressions as series of products of three Bessel functions. In addition, a vortex-free power-function BG beam of the mth order is obtained, which upon propagation in free space becomes a finite superposition of similar vortex-free power-function BG beams of the orders from 0 to m. Extending the set of finite-energy vortex beams with an orbital angular momentum is useful in searching for stable light beams for probing the turbulent atmosphere and for wireless optical communications. Such beams can be used in micromachines for controlling the movements of particles simultaneously along several light rings.
