Abstract
International audienceWe report the first saturated amplification of an optical-field-ionization soft x-ray laser. The amplifying medium is generated by focusing a circularly polarized 330-mJ, 35-fs, 10-Hz Ti:sapphire laser system in a few-mm cell filled with xenon. A gain of 67 cm^-1 on the 4d^95p-4d^95d transition at 41.8 nm in Pd-like xenon and a gain-length product of 15 have been inferred at saturation. This source delivers about 5×10^9 photons per pulse. The influence of the pumping energy and the laser polarization on the lasing output are also presentedKeywords
