Paper Abstract

The motion of previously cooled atoms in a spatial grating formed by lin (perpendicular) lin laser field configuration and the static uniform magnetic field is considered in the case of Fg equals 1 yields Fe equals 1 transition. We show that in the case of high intensity laser fields (when Rabi frequency is greater than Zeeman splitting, Doppler shift, natural width, and detuning) atoms are captured in long-lived coherent population trapping (CPT) state while heating, incoherent photon scattering, and atom-atom photon exchange are strongly reduced. The frequency, the damping time of oscillation, and the localization size are obtained for atoms moving near the bottom of potential wells in the frame of harmonic approximation. Narrowing of vibrational spectral lines due to the CPT-effect is predicted.
