| Abstract: | The time-resolved measurement of the sidelight fluorescence of KrF* formed by a short electron-beam pumping pulse (20 ns FWHM, 19 kA, 860 kV) was performed as a function of both the total pressure ranging from 100 Torr to 400 Torr and the partial F2 concentration (0.1–1.0%). We have estimated the fluorescence yields (FY) for various laser-gas conditions experimentally and the results were compared with numerical predictions. This study indicates a superior amplification performance for a single ultrashort pulse in a low-pressure medium because of the higher FY for KrF*. |
