An experimental study of the propagation of intense laser light in a resonant medium (sodium vapor) has revealed a scattering component which is inconsistent with the Raman scattering spectra of a three-level system in an intense laser field. Spectral and angular characteristics of this component have been studied. It is shown that the occurrence of this component can be explained by a model of a resonant four-wave mixing.

Orientation and alignment relaxation of the 3P2 states of sodium measured at high vapor densities

Orientation and alignment relaxation cross sections have been obtained for the $3^{2}P_{\frac{1}{2}}$ and $3^{2}P_{\frac{3}{2}}$ states of sodium by measuring resonance broadening of Hanle-effect signals at vapor densities up to about ${10}^{15}$ atoms/ ${\mathrm{cm}}^{3}$ . In order to avoid reabsorption of the resonantly scattered light, the Hanle effect is measured in a region close to the wall of a specially constructed vapor cell. The width of the Hanle-effect signals is found to vary linearly with vapor density. The resulting cross sections for orientation and alignment relaxation are compared with theory.Orientation and alignment relaxation cross sections have been obtained for the $3^{2}P_{\frac{1}{2}}$ and $3^{2}P_{\frac{3}{2}}$ states of sodium by measuring resonance broadening of Hanle-effect signals at vapor densities up to about ${10}^{15}$ atoms/${\mathrm{cm}}^{3}$.
