Effect of the trapping laser linewidth on the atom number in a magneto-optical trap, Oct. Chinese Journal of Physics. 38:920-926., Number 5
AbstractWe have experimentally studied the effect of the trapping laser linewidth on the number of capped atoms in a magneto-optical trap (MOT). Our data show that a significant number of the atoms can still be trapped in the MOT, even when the trapping laser linewidth is larger than the natural linewidth of the excited state of the driving transition.

Electron screening and kinetic-energy oscillations in a strongly coupled plasma, Dec 31. Physical Review Letters. 93
AbstractWe study equilibration of strongly coupled ions in an ultracold neutral plasma produced by photoionizing laser-cooled and trapped atoms. By varying the electron temperature, we show that electron screening modifies the equilibrium ion temperature. Even with few electrons in a Debye sphere, the screening is well described by a model using a Yukawa ion-ion potential. We also observe damped oscillations of the ion kinetic energy that are a unique feature of equilibration of a strongly coupled plasma.
