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.
