Abstract
We report the first saturated amplification of an optical-field-ionization soft x-ray laser. The amplifying medium is generated by focusing a circular ly 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(9)5p-4d(9)5d transition a t 41.8 nm in Pd-like xenon and a gain-length product of 15 have been inferr ed at saturation. This source delivers about 5 X 10(9) photons per pulse. T he influence of the pumping energy and the laser polarization on the lasing output are also presented.
