Unique Diagnostic of Magneto Optical Trap Relative Populations
Abstract
In the studies of population trapping, electromagnetically induced transparency, and other processes associated with coherent excitation, knowledge of excited state populations can provide greatly needed insights. However, methodologies often used to determine relative populations in laser-excited system often rely on a model-dependent measurement. Furthermore, lasers used to probe the system can modify the very system one wishes to make measurements on. An accurate, non-intrusive and perusing method has been developed to circumvent this problem. MOTRIMS (Magneto Optical Trap Recoil Ion Momentum Spectroscopy) uses charge transfer as a non-intrusive probe of temporal evolution of excited state fraction, in particular the 5p of Rb. The generalization of these measurements to more complicated systems, e.g. a Rubidium sample having mixture of 5s, 5p, 4d, and Rydberg states will be presented.
