Abstract: We present experimental evidence of the in-phase and out-phase synchronization of the polarization in two coupled quasi-isotropic CO2 lasers. We also show, by means of numerical simulations, how it is possible to retrieve message encoded in the polarization of the master laser from the observation of the slave laser alone, due to the synchronization.
