Laser Cooling: Beyond Optical Molasses and Beyond Closed Transitions

Abstract

We present a simple and general optical cooling method based on 3D degenerate Raman sideband colling with adiabatic release that goes significantly beyond the density and temperature limitations of optical molasses. In 10 ms we cool a sample of 3x10(expn 8) cesium atoms to a temperature of 330 nK at a density of 1.1x10(expn 11) cm (expn -3), which corresponds to a phase-space density n lambda(expn 3 sub dB).
