The dependence of the absorption coefficient for vibration–rotation transitions on ruby-laser pulse intensity and polarization has been investigated experimentally. For linearly polarized radiation, a decrease in absorption is observed as the intensity is increased. For circularly polarized radiation, no decrease is evident, even at significantly higher intensity. A qualitative interpretation of the results is presented.
