Generation of squeezed electromagnetic-field states during the interaction of radiation with optically oriented atoms

The production of squeezed EM states in the nonlinear interaction between classical radiation of frequency omega and a set of optically oriented atoms situated in a magnetic field is studied. Conditions are established under which the polarization of the atoms enhances the parametric generation and, as a result, the squeezing of the field near the frequencies omega + or - Omega sub 0, omega + or - 2Omega sub 0, where Omega sub 0 is the Zeeman splitting frequency of the atomic ground state. Under these conditions, a high degree of squeezing in the scattered light is obtained for incident-light intensities that are much lower than the saturation intensity in the wing of the atomic transition excited.
