Coherent dark states, such as electromagnetically induced transparency (EIT), can be used to control nonlinear effects for light fields [1]. So far, these phenomena have been studied in media involving a macroscopic number of atoms. In order to scale down these systems to the single quantum level of matter (single atoms) and light (single photons) one has to enhance the matter-light interaction. We report on a new experiment where we use a high finesse optical cavity in which an exactly defined number of atoms can be coupled to the mode of the cavity. We discuss prospects for cavity-based EIT with single atoms and will present its first experimental observation.
