Spatial quasi-periodic oscillations of the refractive index in an optically dense medium with a closed excitation contour

К. А. Баранцев, A. N. Litvinov

A closed contour of excitation (Δ-scheme) of a three-level atom in an optically dense medium under the action of two optical fields and a microwave field has been studied. It is found that phase relations between exciting fields in this medium play a determining role. It is established that, under certain conditions, in an optically dense Δ-atom medium exhibits a quasi-periodic dependence of the refractive index on the coordinate. The conditions under which this dependence is most pronounced are determined.

Effect of temperature on quasiperiodic refractive index oscillations in optically dense medium with a closed excitation contour

A theory of a closed contour scheme of excitation ( Δ -scheme) of a three-level atom in an optically dense medium taking into account the effect of temperature is presented. It is shown that spatial quasiperiodic oscillations of the refractive index in this system decay with increasing temperature. The temperature range in which these oscillations are most pronounced is determined.

Control of the index of refraction in optically dense medium

К. А. Баранцев, A. N. Litvinov

In this work we investigate conditions of emergence and destruction of the electromagnetically induced transparency effect in the optically dense medium of atoms which are excited along closed contour of excitation by the three frequency radiation. We found the conditions under which index of refraction of the medium acquires spatial quasi-periodic dependence. It is possible to control this dependence by variation of the initial phases and intensities of the electromagnetic fields.
