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.
