The time-dependent Kr/sub 2/F* fluorescence and KrF* laser emission of an electron beam pumped KrF laser are measured for two gas mixtures, 89.7% Ar/10% Kr/0.27% F/sub 2/ and 99.6% Kr/0.4% F/sub 2/, at initial gas temperatures from 294 to 417 K and for pulse lengths >600 ns. The measurements indicate an inverse square root temperature dependence for the Kr/sub 2/F* formation, which is weaker than earlier predictions. Analysis of the Kr/sub 2/F* and KrF* data also indicates that electron quenching and the effects of gas heating during the pump pulse significantly affect the laser performance of the Kr/F/sub 2/ mixture. Results of a model agree well with the data.
