Dominant formation and quenching processes in E-beam pumped ArF* and KrF* lasers
The dominant formation and quenching processes in E-beam pumped ArF* and KrF* lasers are discussed. The quenching of ArF* by F/sub 2/ and Ar has been measured by analyzing the ArF* (B /sup 2/..sigma../sub 1/2/ ..-->.. X /sup 2/..sigma../sub 1/2/) fluorescence as a function of the F/sub 2/ and Ar partial pressures. We have also measured the displacement of the Ar in ArF* by Kr to form KrF*. The dominant quenching processes of KrF* were identified, and the rate constants were measured. The ArF* and KrF* are formed from the ionic states with high efficiency. Interception of the precursors can be made negligible by choosing the experimental conditions properly. The quenching of KrF* by Ar and Kr is mainly a three-body process resulting in the formation of Kr/sub 2/F*. The emission from Kr/sub 2/F* was observed in a broadband centered at 410 nm. We have verified that the Kr/sub 2/F* is produced subsequent to the KrF* formation by performing a laser saturation experiment.
