Abstract

The results of an experimental campaign on propagating several Laguerre–Gaussian (LG) beams with trivial radial order and their random sequences through the controlled-air turbulence are presented. Various statistical moments of the fluctuating intensity of a single LG mode and the mode-to-mode correlations and their derivatives are found. The mode-to-mode intensity correlations revealed the appearance of robust ring-like structures depending in size on the mode index difference. The experimental results were verified with the help of numerical simulations.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
