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…

Bi-chromatic paraxial beam as a model of spatio-temporal light fields
Aleksandr Bekshaev
Optical fields with rich and well-developed spatio-temporal structure, including ultra-short structured light pulses, are essentially non-monochromatic and contain a continuous spe…

Spatio-temporal optical vortices: principles of description and basic properties
Aleksandr Bekshaev
This compilation represents a summary of the main physical foundations underlying the structure and properties of spatio-temporal optical vortices (STOV). The general approach to t…
