ABSTRACT
The time-dependent Kr2F* 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% F2 and 99.6% Kr/0.4% F2, 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 Kr2F* formation, which is weaker than earlier predictions. Analysis of the Kr2F* 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/F2 mixture. Results of a model agree well with the data.

    We report on a localized high-density electron beam in large-area microwave discharges in argon. The beam is observed only for certain antenna configurations at gas pressures of about 50 mTorr, and it strongly modifies the radial plasma density profiles. The beam current near the quartz plate is...
