A crucial part of these experiments is the preparation of the sodium atoms into the excited state by laser optical pumping. A commercial single-mode Rhodamin 6G continuous wave (cw)-dye laser (Spectra Physics model 580) is used, having 20-40-mW single mode output power when tuned to the sodium resonance line. [Pg.365]

A material increase in the atomic density has been attained in what is known as the dark MOT, wherein the localized atoms are optically pumped to a hyperfine-structure sublevel at which they are off resonance with the main localizing laser field. This method was successfully used to localize sodium atoms by Ketterle et al. (1993). These authors demonstrated a substantial improvement of the trap parameters in comparison with the standard MOT the atomic density amounted to 10 atoms/cm with a large total number of localized atoms (over 10 °). In recent years, the MOT has become the most popular trap for cold atoms. To date, there is a very impressive list... [Pg.105]
