Abstract
The experiments have been performed at 100-J-class GARPUN KrF laser installation, which consists of 20-ns discharge-pumped master oscillator and two stages of e-beam-pumped amplifiers with gain volumes of 10x10x100 cm and 16x18x100 cm. Gain and absorption coefficients were measured in a single-pass scheme, while intrinsic efficiency of about 12% was demonstrated in the saturated double-pass amplification. They were compared with numerical simulations. A numerical code solved a set os simultaneous self-consistent kinetic equations together with amplification of laser radiation and spontaneous emission in large-aperture KrF lasers. Being verfied with the experimental data the code was used to forecast the parameters of IFE-scale KrF amplifiers.
