Spatiotemporal optical vortices: Principles of description and basic properties

A. Bekshaev

Abstract: This compilation represents a summary of the main physical foundations underlying the structure and properties of spatiotemporal optical vortices (STOVs). The general approach to the STOV description and characterization is based on the model of a scalar paraxial Gaussian wave packet. On this ground, the STOV structures of arbitrary orders are considered as superpositions of spatiotemporal Hermite–Gaussian modes. This approach enables a systematic characterization of the main STOV properties in an explicit and… Show more
