Absorption spectroscopy of cold caesium atoms confined in a magneto-optical trap

闫树斌 Yan Shubin, Tao Liu, Tao Geng +3 more

Absorption spectra of cold caesium atoms confined in a magneto-optical trap are measured around D 2 line at 852nm with a weak probe beam. Absorption reduction dip due to electromagnetically induced transparency (EIT) effect induced by the cooling/trapping field in a V-type three-level system and a gain peak near the cycling transition are clearly observed. Several mechanisms mixed with EIT effect in a normal V-type three-level system are briefly discussed. A simple theoretical analysis based on a dressed-state model is presented for interpretation of the absorption spectra.

Observation of dual electromagnetically induced transparencies in cold $^{87}Rb$ atoms

Mishra, Charu, A. Chakraborty, Surjya Prakash Ram +3 more

We have observed two dual electromagnetically induced transparency (EIT) spectra in probe transmission through cold $^{87}Rb$ atoms trapped in a magneto-optical trap (MOT). These dual EIT peaks are generated in two different N-systems formed by probe, coupling and control beams interacting with different levels in $D_{2}$ line transitions of $^{87}Rb$ atom. The dependence of spectral features of two N-systems on driving beams (\textit{i.e.} coupling and control beams) strength and detuning has been investigated. The results show that the dual EIT spectral features in both the N-systems can be manipulated by varying the strength and detuning of both the driving beams. The two N-systems have been modelled theoretically using a density matrix formalism and results have shown a reasonable agreement with the experimental observations.

The Probe Transmission Spectra of 87 Rb in an Operating Magneto-Optical Trap in the Presence of an Ionizing Laser

Long-Wei Liu, Feng-Dong Jia, Ya-Ping Ruan +6 more

The influence of an ionizing laser on the pump-probe spectra of 87 Rb over the transition 5 2 S 1/2 , F = 2 → 5 2 P 3/2 , F' = 3 is experimentally studied in an operating magneto-optical trap. These spectral features, including gain peak, a dispersion-like structure and absorption peak, become weak as the intensity of the ionizing laser increases. Moreover, the profiles of the absorption peak and gain peak vary as the ionizing laser intensity changes. Such results indicate that there is more than one component in the two features and that each component has different dependences on the number of 87 Rb atoms.
