We would like to thank Alberto Domínguez, Santiago Vélez, and Francisco Ruiz-Tagle for their valuable engineering support. We also thank masters’ students Ignacio Rojas, Andrés Seguel, and JoséPablo Durandeau for contributing to the campaign with alignment tasks and measurements. This work has been supported by ANID Chile through grant Fondecyt 1210297. A significant part of the experimental equipment and student scholarships have been provided by the Millennium Science Initiative Program (ANID Chile), through grant ICN17-012.

N2 - 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.
