Polarization-ellipse rotation by induced gyrotropy in sodium vapor

William V. Davis, Alexander L. Gaeta, Robert W. Boyd

We show that for a broad range of intensities the polarization ellipse of a laser beam can undergo rotation while propagating through an atomic vapor. The ellipse rotation is predicted to occur for the case in which the field is tuned near a J = 1/2 to J-1/2 transition of the atomic vapor and the input intensity is sufficiently strong to saturate the ground-state optical pumping but not the transition itself. Under these conditions, the ellipse rotation is independent of the laser intensity and, hence, is unlike the ellipse rotation predicted and observed by Maker and Terhune1 for a tensor nonlinear susceptibility.We show that for a broad range of intensities the polarization ellipse of a laser beam can undergo rotation while propagating through an atomic vapor.

Change in the parameters of a light wave during propagation through a resonant gaseous medium in a magnetic field

А. Ч. Измайлов

A theoretical analysis is made of the resonant interaction between a traveling monochromatic light wave of arbitrary intensity and polarization and the 1/21/2 and 10 transitions in gas atoms in a magnetic field. An analysis is made of the influence of atomic collisions and coherence of the Zeeman sublevels of the terms on the structure of nonlinear magnetooptic resonances in the amplitude and polarization characteristics of the wave. Some features of nonlinear magnetooptic resonances for laser excitation of atoms from the ground state are noted. A study is made of the Faraday rotation and self-rotation of the polarization ellipse of the radiation as a function of the detuning of the wave frequency, the saturation parameter, and the optical density of the gas. The stability of the polarization of light in the medium is discussed. It is noted that these laws may be used to analyze and control the radiation characteristics of lasers and amplifiers when the level of saturation of a resonant gaseous medium in a magnetic field is high.A theoretical analysis is made of the resonant interaction between a traveling monochromatic light wave of arbitrary intensity and polarization and the 1/21/2 and 10 transitions in gas atoms in a magnetic field.
