Superradiant emission of an atomic beam into an optical cavity — •Simon B. Jäger, Haonan Liu, John Cooper, and Murray J. Holland — JILA, National Institute of Standards and Technology, and University of Colorado, Boulder, Colorado 80309-0440, USA

We investigate the different emission regimes of a pre-excited and collimated atomic beam traversing an optical cavity. In the regime where the cavity degrees of freedom can be adiabatically eliminated, we find that the atoms undergo superradiant emission when the collective linewidth exceeds transit-time, homogeneous, and inhomogeneous broadening mechanisms. In this regime we find a superradiant phase where the atomic beam undergoes continuous monochromatic light emission. We analyze the stability of the emission frequency with respect to homogeneous and inhomogeneous frequency shifts and predict the emergence of dynamical superradiant phases where the emission spectrum shows several frequency components.
