Abstract

Abstract The effect of the hyperfine structure of an excited level on the shape of the coherent population trapping (CPT) resonance under Ramsey interrogation is investigated in media with different optical thicknesses. The shape of the CPT resonance is constructed for optically thin and dense media, and the results are compared. The dependence of the light shift on the optical density of a medium is analyzed. The parameters of the field phases are determined for which the light shift remains constant under fluctuations of the optical thickness of the medium.

Line shape and light shift of coherent population trapping resonance under Ramsey interrogation in ‘hot’ atoms in an optically dense medium

Abstract A theory is developed for the effect of coherent population trapping (CPT) in ‘hot’ atoms under pulsed pumping in an optically dense medium with a buffer gas. The case is considered when the excited level is not degenerate. Based on an analysis of the shape of Ramsey resonances, we show that with increasing optical density of the medium, the dependence of the light shifts of the CPT resonance becomes more and more nontrivial. The dependence of the light shifts of the CPT resonance on the magnitude of the hyperfine splitting of the excited level, concentration of active atoms, temperature, and duration of the dark pause is constructed.

We report a study of the Ramsey technique for detecting coherent population trapping resonance in a cold rarified ensemble of atoms with the collective effects related to its finite optical thickness taken into account. It is found that with the growth of the optical thickness of the medium the Ramsey comb becomes shifted with its maxima ‘trimmed’. The possibility of producing a region of maximal atomic excitation near the exit from the medium is found.

In this work we calculate the Ramsey resonances of coherent population trapping effect in cold atomic ensembles. The main goal is to investigate the light shift of the resonance on the different parameters in optically dense medium, because such medium can to distort and absorb the interrogating laser pulses.

In this paper we investigate the effects observed in optical dense medium when detecting the coherent population trapping resonance by the Ramsey method. The cloud of cold atoms interacts with two laser pulses one of which excites the coherent population trapping resonance and the second detects it. The signal of radiation passed through the medium and signal of fluorescence were analyzed. Shifts of the side peaks of the Ramsey fringes are observed with increasing optical density of the medium.

Autobalanced spectroscopy of CPT resonance in an optically dense atomic ensemble

К. А. Баранцев, A. N. Litvinov

We investigate the influence of optical thickness on the coherent population trapping (CPT) resonance interrogated by the autobalanced Ramsey method as well as by the method of combined error signals (CESs). We analyze sensitivity of the CPT resonance to the light shift of the etalon transition for the microwave quantum frequency standards based on cold or hot atomic ensembles. When the CPT resonance is excited, two-frequency laser radiation can be significantly absorbed at the atomic transitions of the optical range. The effects of absorption and phase incursion lead to additional shift of the reference resonance. This is an additional factor that degrades the accuracy of the frequency standards because this additional shift can vary with intensity and temperature fluctuations. It was shown that the CES method is more robust in an optically dense medium than is the autobalanced Ramsey method, but it also undergoes the light shift. We found that by choosing the normalization factor of the CES method it is possible to suppress the light shift for a certain density of the medium or suppress its sensitivity to temperature fluctuations.

Effect of collisions on the shape of the coherent population trapping resonance detected by the Ramsey method

Abstract We report on a theoretical model of the effect of coherent population trapping in alkali atoms in an optically thin gas cell with a buffer gas at a nonzero temperature in a pulsed laser field. The shape of the Ramsey resonance is analysed for two different temperature ranges, i. e. for a ‘cold’ atomic ensemble and for an ensemble of ‘hot’ atoms in a cell with a buffer gas. The influence of the hyperfine structure of the excited level on the shift of the central Ramsey resonance is investigated.
