Resumen:
Experimental evidence and theory on the head-on excitation of atoms by paraxial Laguerre-Gaussian beams revealed that the longitudinal component of the field has to be taken into account. Optical vortices are in fact a large family of fields, Laguerre-Gaussian being only one particular case. Here we extend the previous study to a broader set of vortex fields. We demonstrate that, in general, paraxial optical vortices that have opposite orbital and spin angular momenta exhibit a longitudinal component that cannot be disregarded in the light-matter interaction.
