Long-distance Bessel beam propagation through Kolmogorov turbulence

Localized Bessel Beams: Basic Properties and Emerging Communication Applications

“…An efficient FSO communication system should have a transmission beam as small as possible, with high peak intensity and high power. As deeply discussed in [18], these criteria are fully satisfied by Bessel beams. First of all, thanks to relation (15), the aperture radius required for a Bessel beam to transmit the half power is smaller than that required by a Gaussian beam, with a reduction of about 25% [18].…”

First of all, thanks to relation (15), the aperture radius required for a Bessel beam to transmit the half power is smaller than that required by a Gaussian beam, with a reduction of about 25% [18]. Furthermore, when comparing Bessel and Gaussian beams generated with the same aperture, the peak intensity of Bessel beam results to be about 1.2 times greater than that of the Gaussian beam.…”

“…The presented results are taken from [18], vertical axis giving the radial distance in [m] and horizontal axis representing the propagation distance in [km]. The outperformances of Bessel beams are clearly visible.…”

Realization of Free‐Space Long‐Distance Self‐Healing Bessel Beams

“…Due to their excellent self‐healing capabilities, they may take a superior role in free‐space terrestrial and satellite communication . Recent studies suggest that Bessel beams are well suited for stable long‐range communication through turbulent media . However, these theoretical considerations have to assume a technology which surpasses currently achievable propagation lengths by far.…”
