Accelerated superradiance and collective atomic recoil lasing with a two-frequency pump / M. Cola, L. Volpe, N.U.C. Piovella. - In: PHYSICAL REVIEW A. - ISSN 1050-2947. - 79:1(2009), pp. 013613.013613.1-013613.013613.5. [10.1103/PhysRevA.79.013613]
Abstract:
We demonstrate that superradiance and collective atomic recoil lasing from cold atoms can be enhanced using a two-frequency pump with frequency difference twice the two-photon recoil frequency ωr. In the good-cavity regime the atoms behave as a three-recoil-level system, collectively scattering a single-frequency radiation mode. In the bad-cavity regime, the superradiant cascade through the different recoil momentum states is strongly accelerated. The emitted radiation shows a discrete spectrum whose harmonics are separated by 2 ωr and generated by transitions between adjacent momentum levels.
