Paper Abstract

The possibility of using rare gas atoms as the active species in an optically pumped laser is considered. Rg(np5(n+1)s) metastable states may be produced using low-power electrical discharges. The potential then exits for optical pumping and laser action on the np5(n+1)p↔np5(n+1)s transitions. Knowledge of the rate constants for collisional energy transfer and deactivation of the np5(n+1)p states is required to evaluate the laser potential for various Rg + buffer gas combinations. In the present study we have characterized energy transfer processes for Ne (2p53p) + He for the six lowest energy states of the multiplet. Deactivation of the lowest energy level of Kr (4p55p) by He, Ne and Kr has also been characterized. Preliminary results suggest that Kr (4p55p) + Ne mixtures may be the best suited for optically pumped laser applications.
