Narrow linewidth gain measurements in a KrF excimer amplifier pumped longitudinally by a high-power electron beam
Single-pulse gain measurements have been performed on an excimer amplifier pumped longitudinally by a high-power (approx.4 MW/cm/sup 3/) electron beam. This amplifier maintained the narrow linewidth (<10 GHz) characteristic of the probe laser beam produced by a grating-tuned, discharge excimer laser. Gain was measured at 248.45 nm, the center of the KrF laser gain profile, over four orders of magnitude of input intensity for a laser pulse of 20-ns FWHM. The data an be represented by the Rigrod-Rice steady state analysis and yield values over this data range for the small signal gain, the nonsaturable absorption, and saturation intensity of g/sub 0/ = 12.6%/cm, ..cap alpha.. approx. 0.45%/cm, and I/sub s/ = 4.1 MW/cm/sup 2/, respectively, for a 750 torr laser mix. 4 refs.
