We experimentally demonstrate two applications of the cooperative interactions of light with a cold atomic gas in an optical resonator. Although the atoms are individually coupled weakly to the resonator mode, collective coupling gives rise to effects reminiscent of the strong coupling regime. We apply this collective coupling to the laser cooling of cesium atoms, and to the creation of a source of single photons.

520 $a We experimentally demonstrate two applications of the cooperative interactions of light with a cold atomic gas in an optical resonator. Although the atoms are individually coupled weakly to the resonator mode, collective coupling gives rise to effects reminiscent of the strong coupling regime. We apply this collective coupling to the laser cooling of cesium atoms, and to the creation of a source of single photons.
520 $a We first show that resonator-induced light forces arising from cooperative atom-light interactions in a many-atom sample can lead to a dramatic increase in the efficiency of laser cooling. We observe collective Raman emission by 106 cesium atoms in the mode of an optical resonator, driven by pump beams tuned close to the atomic resonance. This emission leads to sub-Doppler cooling of the atoms, with final temperatures as low as 4 muK.
520 $a In a far-detuned regime in which the atoms behave as two-level particles, the driven atoms self-organize into a density grating that efficiently Bragg scatters light into the cavity mode at a rate per atom that is 104 times larger than that expected for a single atom. Bragg scattering induces strong damping of the atomic center-of-mass velocity, with decelerations of 104 m/s2 for atoms with initial velocity of 1 m/s. The emission and damping mechanism can exert large impulse even when driving an open optical transition. Measurements of the phase of the emitted light demonstrate spontaneous symmetry breaking in the formation of the atomic density grating.
520 $a We have further applied cooperative intracavity atomic light-scattering processes to the problem of single-photon generation. Following the protocol of Duan et al. [Nature 414, 413 (2001)], we have implemented a two-step Raman process for the storage of a photonic excitation as an atomic spin grating and the subsequent reconversion of that excitation into a photon in the resonator mode. Efficiencies for photon retrieval of 40% have been observed in the single-photon limit, with photon storage times of 3 mus, limited by Doppler decoherence. Measurements of phase matching conditions demonstrate the collective nature of the photon emission.
