“…As well as the scintillation, beam wander is an important characteristic of laser beams, which determine their utility for practical applications such as free-space-optical communication and pointing [24]. In recent years, beam wander has been studied for a variety of beams with different modes [25][26][27][28][29].

The beam wander of a partially coherent Airy beam in a turbulent atmosphere was investigated. By using the extended Huygens-Fresnel integral, as analytical expression is derived for the second-order moment of a partially coherent Airy beam. Based on the theory proposed by Andrews, a general expression is obtained for the beam wander of a partially coherent Airy beam. With the help of the expression, various factors which impact on the beam wander are illustrated numerically. The results show that the beam wander of a partially coherent Airy beam decreases with the increase of the characteristic scale and the decrease of the coherent length or the exponent truncation factor. The value of the beam wander is a maximum when the exponent truncation factor is 0.63, no matter what the coherent lengths are. Our results provide an effective way to control the beam wander of a partially coherent Airy beam in practice.

“…Considerable effort has been devoted to the formulation of beam-wander variance for various types of optical beams [1][2][3][4][5][6]; the effect of the partial coherence of the source on the beam-wander variance was also studied by Berman et al [7], followed by Xiao and Voelz [8] and Yu et al [9]. The dynamics of beam wander are manifested in their temporal spectra.…”

The temporal spectrum of beam wander is formulated by considering a Gaussian Schell-model beam passing through atmospheric turbulence with a finite outer scale. Two simpler asymptotic formulas for the temporal spectrum of beam wander within the high- and low-frequency ranges are derived, respectively. Based on the formulations, the effects of the initial partial coherence of the beam, finite outer scale of turbulence, initial beam radius, and initial phase front radius of curvature on the temporal spectrum of beam wander are analyzed by numerical examples.

“…Beam wander is an important characteristic of a laser beam, which determines its utility for practical applications such as uninterrupted laser tracking and free-spaceoptical communication [7]. In the past five decades, beam wander for a variety of beams with different shapes has been studied [8][9][10][11][12][13][14][15][16][17]. These works show that the beam wander can be influenced by many factors, including the initial spatial coherence length [8][9][10][11], amplitude factor [12], source size [13,14], degree of polarization [15], topological charge [16], divergence and convergence [17], and the turbulence [8][9][10][11][12][13][14][15][16][17].…”
