Аннотация
Vortex Bessel beams with topological charges l=pm 1 and l=pm 2 were generated with diffractive optical elements in the THz range using monochromatic and tunable radiation of the Novosibirsk free electron laser. Diffractive and interference techniques were applied to study the main characteristics of the vortex beams, i.e. topological charge and pitch-factor. Analytical studies, simulations and experimental results are given.
