Spectroscopy of cold, trapped atoms

  • Published:
Acta Physica Hungarica B) Quantum Electronics

Abstract

We describe the results of the pump-probe spectroscopy performed with 85Rb atoms trapped in a magneto-optical trap (MOT). We show how various processes associated with light-atom interactions shape the observed spectra and how their features can be utilized for obtaining information about properties of cold-atom sample. In particular, we emphasize the important role of the atomic-recoil phenomenon and use it for efficient and reliable velocimetry of the working MOT.

  25. In some situations, for example when momentum distribution is asymmetric, its width cannot be properly defined. We have observed such distributions in our experiment when the trapping beams were not accurately aligned and their detuning from atomic resonant frequency was decreased [6].
