Phys. Rev. Lett. 94, 053604 (2005) [4 pages]Transition from Antibunching to Bunching in Cavity QEDReceived 4 June 2004; published 10 February 2005 The photon statistics of the light emitted from an atomic ensemble into a single field mode of an optical cavity is investigated as a function of the number of atoms. The light is produced in a Raman transition driven by a pump laser and the cavity vacuum, and a recycling laser is employed to repeat this process continuously. For weak driving, a smooth transition from antibunching to bunching is found for about one intracavity atom. Remarkably, the bunching peak develops within the antibunching dip. The observed behavior is well explained by a model describing an ensemble of independent emitters. © 2005 The American Physical Society URL:
