Referent: Prof. Dr. Dieter Meschede2.t: Prof. Dr. Martin WeitzTag der Promotion: 15.09.2009AbstractIn this thesis I present an experimental realization of controlled systems consisting oftrapped neutral atoms strongly coupled to a high-finesse optical resonator. These systemsenable the exploration of atom-light interaction at the most fundamental level, and havea potential application in quantum information processing.Experimental tools for preparation, detection and transport of individual Caesiumatoms into the cavity mode are presented. In addition, the setup and properties of theresonator are discussed.I investigate two different methods to detect the atom-cavity interaction. The firstapproach relies on the observation of the cavity transmission, which allows us to contin-uously monitor the interaction dynamics of a single atom coupled to the resonator modefor several seconds. Using this approach I characterize the system and investigate thedependence of the coupling strength on the number of atoms and their position inside thecavity mode.
