The light and orientation end resonance frequency shifts in alkaline atoms vapors

Abstract

The results of analytical studies of the Light shift effect in the end resonance regime are presented. When linear polarized pumping is employed significantly smaller frequency shift (2 orders of magnitude less) can be obtained in comparison to circular polarized light. Yet, the results of diagonal elements of the density matrix calculations show that such pumping mode leads to 2-3 times atoms polarization loses on working transitions.
