My research is focused on the study of coherent control of a particular type of cold collision known as photo-association (PA). In this process, a laser is used to place pairs of neighboring cold atoms having temperatures of ~120 microkelvin, into an electronically excited, bound, molecular state. If allowed to decay, these molecules, having typical internuclear separations of ~50 nanometers, would normally decay back into separate ground state atoms, though they can occasionally decay to bound electronic ground states of the molecule. In our case, some fraction of the excited molecules are further excited into autoionizing molecular states. The resulting molecular ions are readily extracted and used as a measure of how efficiently PA + excitation (PAE) takes place.
