Parametric characterization of vortex cosine-hyperbolic-Gaussian beams
Based on the moments method, the analytical expressions for the beam propagation factor, the kurtosis parameter and the orbital angular momentum density distribution of a vortex cosh-Gaussian beam (vChGB) propagating in free space are derived. According to the obtained expressions, the beam propagat...
