Based on a simple one-dimensional model, we consider the effect of trapped-ion heating on the efficiency of generalised Ramsey methods for the probe-induced frequency shift suppression in optical frequency standards based on single ultracold ions. It

The possibility of precision measurements of frequencies of forbidden transitions of cold atoms in a trap using stimulated Raman scattering is shown. Transition 1S–2S in a hydrogen atom, in which the atom passes from level 1S to level 2S via interm

We demonstrate the possibility of measuring the forbidden 21S0 – 23S1 transition frequency (λ = 1557 nm) of a helium atom by the method of stimulated Raman scattering through the intermediate 23P1 level. Singlet (21S0) and triplet (23S1) states ha

Using the atomic density matrix formalism, we investigate the dynamic regime of formation of the error signal for resonances of coherent population trapping excited in a three-level Λ-system by a bichromatic field. The optimal parameters of harmonic

We report on an experiment in which the decay time of an oscillating fluorescence of rubidium atoms on a 5P state in a coated vapor cell exceeds several of milliseconds; that is, many orders of magnitude longer than the normal decay time of the excit
