In this article, the authors present an amplitude damping channel for Laguerre-Gaussian modes. The channel is tested experimentally for a Laguerre-Gaussian mode, having an azimuthal index l = 1, illustrating that it decays to a Gaussian mode in good agreement with the theoretical model for amplitude damping. Since the authors are able to characterize the action of such a channel on orbital angular momentum states, they propose using it to investigate the dynamics of entanglement.
