Abstract :
In the present paper, we demonstrate a new method to obtain orbital angular momentum spectrum on the basis of electric-field reconstruction in spatial domain from interferograms, without using diffraction effects. Our method is applicable to ultrabroadband optical vortices, even in few-cycle regime.
