我们报道了第一个饱和放大的光场电离软x射线激光器。放大介质是通过将圆偏振330-mJ， 35-fs， 10-Hz的Ti：蓝宝石激光系统聚焦在充满氙气的几毫米电池中产生的。在类pd氙气中，在41.8 nm处的4d(9)5p-4d(9)5d跃迁上的增益为67 cm(-1)，在饱和时的增益长度乘积为15。该源每脉冲提供约5 x 10(9)个光子。给出了泵浦能量和激光偏振对激光输出的影响。
We 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(9)5p-4d(9)5d 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 x 10(9) photons per pulse. The influence of the pumping energy and the laser polarization on the lasing output are also presented.
