Laser Cooling: Beyond Optical Molasses and Beyond Closed Transitions

reportActive / Technical Report | Accession Number: ADA640000 | Open PDF

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 3x10expn 8 cesium atoms to a temperature of 330 nK at a density of 1.1x10expn 11 cm expn -3, which corresponds to a phase-space density n lambdaexpn 3 sub dB.
