Abstract

We present an experimental campaign consisting on the propagation of laser modes with orbital angular momentum (OAM), carried out in our campus, for a total propagation distance of 1 kilometer. In this proceedings article we describe our experiment and describe some preliminary results, using topological charges up to |ℓ| = 45. We also demonstrate that a Shack-Hartmann sensor may be used for OAM sensing in the presence of weak to intermediate turbulence without the help from adaptive optics.
