This paper reports on the gain characteristics of an electron-beam pumped XeF(C {yields} A) excimer amplifier operating in the blue-green spectral region that were investigated for several laser pulse lengths. Saturation energy densities of 50 and 80 mJ/cm{sup 2} were measured for injected laser pulse durations of 250 fs and {approximately}100 ps, respectively. A gain bandwidth of 60 nm was observed with {approximately}100 ps pulse injection. Using an optimized unstable resonator design, the laser amplitude has produced 275 mJ pulses with a pulse duration of 250 fs and a 2.5 times diffraction limited beam quality, making the XeF (C {yields}A) amplifier the first compact laser system in the visible spectral region to reach peak powers at the terawatt level.
