Abstract:

We have carried out a series of experiments to study collisional and radiative processes in alkali metal and alkaline-earth vapors. Our principal interest has been to understand fundamental atom-atom, atom-molecule, and atom- light interactions in order to model alkali diatomic and alkaline-earth excimer systems for possible laser applications. During this funding period, we have concentrated on collisional excitation transfer, quenching and diffusion processes involving the metastable 6s5dD sub J levels of barium. We have also investigated alkali and alkaline-earth vapors as media for observing low threshold nonlinear optical processes
