Abstract
Parametric dependence of the time dependent fluorescence spectrum of an e-beam pumped KrF laser medium was investigated in a high current density range of 120 to 250 A/cm2. Higher optimum pressure and shorter pulse duration were the prominent features. The results were fitted with a proposed rate equation model, indicating that the high current density e-beam pumping is favorable for high efficiency laser operation mainly because of a great deal of reduction of the three body quenching rate at higher temperature. A possibility of generating 25m J/cm3 of 250 nm photons with an efficiency of 8% was predicted.Keywords
