Abstract

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 in an Elliptically Polarized Light Field

Denis V. Brazhnikov, А. В. Тайченачев, Anatolii M Tumaikin +4 more

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 resonance amplitude in the case of elliptic polarization of the light wave can be the order more than for linear polarization.

Effect of Laser Light Ellipticity on Hanle Electromagnetically Induced Absorption Amplitude and Line Width

Jelena Dimitrijević, Z. D. Grujić, Marina M. Mijailović +3 more

Using the 2 S 1/2 Fg = 2 -→ 2 P 3/2 Fe = 3 transition in 87 Rb, we analyzed the interaction between the arbitrarily polarized laser light and Zeeman sublevels in the Hanle configuration.We studied theoretically and confirmed experimentally that the effect of the laser light polarization on the electromagnetically induced absorption strongly depends on the laser light power.For the same atomic transition, and for single laser light power (3 mW), it was recently shown that electromagnetically induced absorption line widths increase with polarization ellipticity and that electromagnetically induced absorption amplitude has maximum for certain laser light polarization different than linear.Here, we present results for amplitudes and widths of electromagnetically induced absorption for different laser light polarizations and for the laser light power ≤ 200 µW.It is verified that for small laser light power maximal electromagnetically induced absorption amplitude is for the linear polarization, whereas for larger power maximum of the electromagnetically induced absorption is at higher polarization ellipticity.

Nonlinear magneto-optical rotation of elliptically polarized light

Andrey B. Matsko, Irina V. Novikova, Muhammad Suhail Zubairy +1 more

We predict theoretically and demonstrate experimentally an ellipticity-dependent nonlinear magneto-optic rotation of elliptically polarized light propagating in a medium with atomic coherence. We show that this effect results from hexadecapole and higher-order moments of the atomic coherence, and is associated with an enhancement of Kerr and higher-order nonlinearities accompanied by suppression of the other linear and nonlinear susceptibility terms of the medium. These nonlinearities might be useful for quantum signal processing. In particular, we report an observation of enhancement of the polarization rotation of elliptically polarized light resonant with the ${5S}_{1/2}F=\stackrel{\ensuremath{\rightarrow}}{2}{5P}_{1/2}F=1$ transition of ${}^{87}\mathrm{Rb}.$
