Direct Measurement of the Topological Charge in Elliptical Beams Using Diffraction by a Triangular Aperture
We introduce a simple method to characterize the topological charge associated with the orbital angular momentum of a m-order elliptic light beam. This method consists in the observation of the far field pattern of the beam carrying orbital angular momentum, diffracted from a triangular aperture. We...
