title: Dependence of the absorption coefficient of vibration-rotation transitions of dipole molecules on the resonance radiation polarization.
abstract: 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.
