Watching Coherent Control and Dynamics using MOTRIMS
Professor Hai Nguyen is interested in using MOTRIMS (Magneto Optical Trap Recoil Ion Momentum Spectroscopy) as a tool to study Coherent Control and Dynamics. Extremely cold Rubidium atoms are cooled and trapped in a Magneto Optical Trap (MOT) to be used as a target sample to probe at Coherent processes such as STIRAP (stimulated Raman adiabatic passage). STIRAP will be done on cooled and trapped 87Rb using shaped ultrafast pulses of light, and the time evolution of the electronic levels will be measured on the few ns timescale via MOTRIMS. STIRAP is an important protocol for efficiently placing an atomic or molecular system into a single desired state. As such it holds great promise in quantum information, atom optics, and in the control of chemical reactions.
