High-intensity wave vortices in the beamoptics domain: 3D spatial structure, singleplane models, and their propagation properties
I. Mokhun, O. Angelsky, A. Bekshaev +2
Typically, vortices in wave fields are associated with amplitude zeros. In contrast, recently described high-intensity (Type II) wave vortices appear near amplitude poles and can e…

Wigner function and intensity moments of spatio-temporal light fields
Aleksandr Bekshaev, Oleg Angelsky, Claudia Zenkova
The Wigner distribution function and its spatial-angular moments (intensity-moments) are known as efficient instruments for characterization of complex quasimonochromatic light bea…
