Small Scale Discharge Studies
Abstract
Laser action has been obtained in atmospheric-pressure mixtures containing approx. 95% Ar approx. 5% Kr and < or = 0.3% F2 by e-beam controlled discharge pumping. The physics of these discharges are dominated by electron impact excitation and ionization of the rare gas metastables. The ionization of the metastables impacts the discharge stability directly while their excitation strongly effects the efficiency of producing KrF*. Hence, two step ionization is dominant. For stable equilibrium, the attachment rate has to be greater than or equal to twice the ionization rate. Under stable discharge conditions, the metastable production efficiency can be as high as 70% and the KrF* production efficiency 35%.
