Title: Diffractive coupling between radial and angular modes in optical
vortices

Abstract: Diffractive coupling between radial and angular modes in
optical vortices
Resumo: In this work we use an SLM encoded with an hologram made of a
product of two Laguerre-Gaussian modes to show that by only changing the
angular degree of freedom we are able to control the radial structure of
the beam, The output modes are decomposed as a superposition of modes
with different radial orders and their coefficients  calculated.
Experimental demonstration and numerical evaluation agree with
theoretical predictions.
