Abstract

A terawatt-class laser system based on the amplification of tunable femtosecond pulses in an electron beam pumped XeF(C-A) excimer amplifier is reported. For this system the characteristics of gain, saturation, energy, and pulse shape is described theoretically and experimentally, particularly their dependence on input pulse duration, gain length product, and nonsaturable absorption. Using an optimized unstable resonator, this XeF(C-A) laser system generates 275 mJ, 250 fs pulses at 490.5 nm.
