Generation of “perfect” vortex of variable size and its effect in angular spectrum of the down-converted photons
The “perfect” vortex is a new class of optical vortex beam having ring radius independent of its topological charge (order). One of the simplest techniques to generate such beams is the Fourier transformation of the Bessel-Gauss beams. The variation in ring radius of such vortices require Fourier le...
