Abstract

We report the 1-D cooling of 85Rb atoms using a velocity-dependent optical force based upon Ramsey matter-wave interferometry. Using stimulated Raman transitions between ground hyperfine states, 12 cycles of the interferometer sequence cool a freely-moving atom cloud from 21 μK to 3 μK. This pulsed...
