• Abstract: The paper considers the propagation of Laguerre-Gaussian beams in a turbulent gas medium. As demonstrated by numerical modelling and the decomposition of Laguerre-Gaussian modes according to the basis of orthogonal Zernike polynomials, disparities in the stability of Laguerre-Gaussian modes with differing radial and azimuthal numbers are evident. The demonstration is made of the minimization of the distortion of the transverse beam profile with an increase in the radial number.

  By employing x-Bohm theory and p-Bohm theory, we construct the position and momentum trajectories of single-mode and superposed-mode Laguerre-Gaussian beams. The dependence of divergence velocity and rotation velocity on the initial position and propagation distance is quantified, indicating that LG beams exhibit subluminal effects, even in free space.

  Orbital Angular Momentum (OAM) modes are an important resource used in various branches of quantum science and technology. We present a theoretical approach to the generation of correlated Schmidt modes carrying OAM via parametric down-conversion (PDC) We demonstrate how the number of generated modes and their population can be controlled by varying the pump parameters.
