Abstract: We study experimentally and theoretically the polarization alternation during the switch-on transient of a quasi-isotropic CO2 laser emitting on the fundamental mode. The observed transient dynamics is well reproduced by means of a model which provides a quantitative discrimination between the intrinsic asymmetry due to the kinetic coupling of molecules with different angular momenta, and the extrinsic anisotropies, due to a tilted intracavity window. Furthermore, the experiment provides a numerical assignment for the decay rate of the coherence term for a CO2 laser. (C) 2003 Published by Elsevier Science B.V.
