Electromagnetically Induced Transparency in optically trapped rubidium atoms
Bernd Kaltenhäuser, Harald Kübler, Andreas Chromik +3
We demonstrate electromagnetically induced transparency (EIT) in a sample of rubidium atoms, trapped in an optical dipole trap. Mixing a small amount of -polarized light to th…

High Resolution Rydberg Spectroscopy of ultracold Rubidium Atoms
Axel Grabowski, Rolf Heidemann, Robert Löw +2
We present experiments on two-photon excitation of Rb atoms to Rydberg states. For this purpose, two continuous-wave (cw)-laser systems for both 780 nm and 480 nm have…

Depolarisation cooling of an atomic cloud
S. Hensler, A. Greiner, J. Stuhler +1
We propose a cooling scheme based on depolarisation of a polarised cloud of trapped atoms. Similar to adiabatic demagnetisation, we suggest to use the coupling between the internal…
