Paper Abstract

Amplification of blue-green (470-490 nm) femtosecond pulses in a gaseous active medium of a photolytically driven XeF(C-A) laser amplifier is studied experimentally. The active medium is optically pumped by the vacuum-ultraviolet radiation from two large-area multichannel surface discharges initiated along opposite planes of the amplifier cavity. The amplification factors exceeding 100 are obtained in a multipass optical scheme in the regime of homogeneous gain distribution over a beam cross-section of up to 3 cm in diameter. A small-signal gain of 0.002 cm-1 is observed at 488 nm for the continuous radiation of Ar-ion laser and for the 150 fs seed pulses as well. The registered spectra insure a good conservation of the temporal characteristics of amplified ultrashort pulses.
