We describe the motion of an atom in a quantized light field using the concept of the Wigner distribution in phase space. This approach provides a pictorial explanation of the deflection and focusing of the atomic beam.

Recent progress in production and control of the atomic wave-packets calls for re-examination of the most fundamental quantum optical processes. We have examined the evolution of the atomic wave-packet resonantly driven by the monochromatic laser beam and the spontaneous emission from an extended atom. We stress the role of Doppler shifts in the dephasing of the atomic dipole. New effects of single laser pulse photon echo and homogeneous Doppler modification of the emission line are discussed.

Wave fields play a central role in both classical and quantum mechanics. Generally applicable methods for the characterization of (scalar) fields are outlined, and illustrated by experiment and simulation.

We have designed a gravitational cavity for ultra-cold atoms using an atomic mirror made from an evanescent laser wave. By a temporal variation of the evanescent wave intensity, we have realized various atom optics components such as temporal slits and phase modulators. We have also designed an atom interferometer using this cavity which proves that the coherence of the de Broglie waves can be preserved during the bounce of the atoms on the mirror. Finally we show that an efficient cooling of the atoms inside the cavity can be achieved using a Sisyphus process during the bounce.

High Resolution Spectroscopy of Cold, Trapped Atoms

Pump-probe spectroscopy of cold, trapped atoms is discussed with particular attention to mechanisms specific for cold atoms and potential diagnostics applications. The discussion is illustrated with experimental results obtained with ^{85}Rb atoms trapped in a magneto-optical trap. Most important applications are non-destructive, real-time velocimetry (thermometry) and analysis of optical lattice dynamics.
