    "abstract": "We report the observation of collective-emission-induced, velocity-dependent\nlight forces. One third of a falling sample containing 3 x 10^6 cesium atoms\nilluminated by a horizontal standing wave is stopped by cooperatively emitting\nlight into a vertically oriented confocal resonator. We observe decelerations\nup to 1500 m/s^2 and cooling to temperatures as low as 7 uK, well below the\nfree space Doppler limit. The measured forces substantially exceed those\npredicted for a single two-level atom.",
