Abstract :
The properties of an optically probed atomic medium can be changed dramatically by coherent interaction with a near-resonant control light field. The authors present experimental results on the elementary case of electromagnetically induced transparency (EIT) with a single neutral atom inside an optical cavity probed by a weak field. The modification of the dispersive and absorptive properties of a single atom by changing the frequency of the control light field in the off-resonant regime is observed.
