Paper Abstract

The approaches to realize superslow relaxation receive growing attention for its correspondence to sharp optical resonance in frequency domain and to long term of information storage in time domain. Dephasing time as long as 2.6 mS was observed in the condensed matter of crystal under the temperature of 1.4K [1]. In RF ion trap Yb ion has been kept in its metastable excited state for 8 days [2]. Population trapping is one of the interested approaches recently. While most papers discussed it for Λ- or V-type three-level systems, Agarwarl et al has theoretically predicted the possibility of population trapping been established by frequency modulated laser field in two-level system [3]. The authors has demonstrated population trapping in high-lying state doublet and in intermediate state doublet via quantum interferences between two sum-frequency two-photon excitations in Y- and in rhomb-type four-level systems respectively [4].
