摘要

We present a numerical investigation of the parameters characterizing the recombination gain in the Lilll 2 → 1 transition (13.5nm). The numerical model includes the initial Optical Field Ionization (OFI) of the plasma by an intense 100f's laser pulse, taking into account ATI heating, particle collisions and spatial effects. Gain is then calculated during the process of recombination as the plasma expands and cools down. We characterize the behavior of the gain under different pumping parameters and initial plasma conditions. In addition we present the latest experimental results on Raman amplification of ultrashort pulses in the pursuit for a better and more compact scheme to enable a "table-top" x-ray laser.
