“…The results in those papers showed that the beam wander decreases as the topological charge of the vortex phase increases. Funes et al carried out experimental measurement of the beam wander of a Gaussian beam against the propagation length through indoor artificially convective turbulence [114], and Kaushal et al studied the beam wander of a Gaussian beam under varying atmospheric turbulence condition in an optical turbulence generator chamber [115].…”

Partially coherent beam is preferred in many applications, such as free-space optical communications, remote sensing, active laser radar systems, etc., due to its resistance to the deleterious effects of atmospheric turbulence. In this paper, after presenting a historical overview on propagation of optical beams in turbulent atmosphere, we describe the basic theory for treating the propagation of optical beams in turbulent atmosphere and we mainly introduce recent theoretical and experimental developments on propagation of partially coherent beam in turbulent atmosphere. Recent progress on the interaction of a partially coherent beam with a semirough target in turbulent atmosphere and the corresponding inverse problem are also reviewed.

“…The geometrical arrangement was similar to that used by Consortini et al [45], and Consortini and O'Donnell [46]. However, a folded path instead of the linear one [64] and expanded and colhmated laser beams with diameters up to 50 mm [65] were also used. Temperatures along the laser beam path, for each record, were measured and stored.…”

“…The beam wander is as important as scintillation in determining the system performance [3]. Accordingly, beam wander of laser beams through atmospheric turbulence has been studied extensively considering the turbulence spectrum models including the Kolmogorov spectrum, von Karman spectrum, and Tatarskii spectrum, as in [2][3][4][5][6][7][8]. However, the atmospheric turbulence defined as non-Kolmogorov turbulence exhibits non-Kolmogorov statistics, where the structure function of the index of refraction and the corresponding power spectrum are assumed to obey arbitrary power laws [9].…”

Beam wander of partially coherent array beams through non-Kolmogorov turbulence

Based on the theory of second moments and non-Kolmogorov spectrum, the beam wander theory is extend to non-Kolmogorov turbulence, the general analytical expression of beam wander in non-Kolmogorov turbulence is derived. Beam wander depends on the non-Kolmogorov turbulence parameters and the initial second moments of the laser beam at the input plane. Taking the Gaussian Schell model array beams as an example, the effects of the generalized exponent parameter, inner scale, and outer scale of non-Kolmogorov turbulence and the beam separation distance, beam number, and coherence degree on the beam wander are studied in detail. It has been shown that the beam wander varies non-monotonically with increasing generalized exponent parameter of the turbulence. Furthermore, it increases as the inner scale decreases or outer scale increases, and decreases as the beam separation distance and beam number increase and the coherence of the beam becomes weaker. Our results also indicate that the beam wander could be reduced by adjusting the beam parameters appropriately.
