Cooling of rubidium atoms in pulsed diffuse laser light

doi:10.1088/1674-1056/20/2/023701

Abstract This paper reports an experiment on laser cooling of ⁸⁷Rb atoms in pulsed diffuse light, which is the key step towards a compact cold atom clock. It deduces an empirical formula to simulate the pulse cooling process based on the loading of cold atoms in cooling time and the loss in the dead time, which is in agreement with the experimental data. The formula gives a reference to select the parameters for the cold atom clock.

Keywords: diffuse light pulsed cooling rubidium atom clock
