Abstract

Electromagnetically induced absorption (EIA) in Hanle configuration versus ellipticity of an optical running wave is investigated. All theoretical results are confirmed experimentally quite well. It is shown that magneto-optical resonance parameters (amplitude, width and amplitude-to-width ratio) depend on the wave polarization substantially. For example, the rsonance amplitude in the case of elliptic polarization of th elight wave can be the order more than for linear polarization.

Features of magneto-optical resonances in an elliptically polarized traveling light wave

D. V. Brazhnikov, A. V. Taĭchenachev, A. M. Tumaĭkin +5 more

The parameters of nonlinear absorption magneto-optical resonances in the Hanle configuration have been studied as functions of the ellipticity of a traveling light wave. It has been found that these parameters (amplitude, width, and amplitude-to-width ratio) depend strongly on the polarization of the light wave. In particular, the resonance amplitude can increase by more than an order of magnitude when the polarization changes from linear to optimal elliptic. It has been shown that this effect is associated with the Doppler frequency shift for atoms in a gas. The theoretical results have been corroborated in experiments in Rb vapor.

Electromagnetically induced absorption and transparency in magneto-optical resonances in an elliptically polarized field

Denis V. Brazhnikov, Anatolii M Tumaikin, Valeriy I. Yudin +1 more

Using a 1 --> 2 transition as an analytically tractable model, we discuss in detail magneto-optical resonances of both electromagnetically induced absorption (EIA) and electromagnetically induced transparency (EIT) types in the Hanle configuration. The analysis is made for an arbitrary rate of depolarizing collisions in the excited state and an arbitrary elliptical field polarization. The obtained results clearly show that the main reason for the EIA subnatural resonance is the spontaneous transfer of anisotropy from the excited level to the ground level. In the EIA case we predict the negative structures in the absorption resonance at large field detuning. The role of the finite atom-light interaction time is briefly discussed. In addition we study nontrivial peculiarities of the resonance line shape related to the velocity spread in a gas.
