| Zusammenfassung | We present a novel method for laser cooling of atoms close to the one-dimensional recoil limit. This method is particularly suited for atoms not accessible to conventional sub-Doppler cooling methods. It is based on the repeated selection and accumulation of slow atoms from a pre-cooled atomic cloud and on the repeated rethermalization of the remaining atoms. The prepared ensemble is used to measure atom interferences with increased visibility. |
