This paper described the efforts to produce short-pulse collisionally pumped soft-x-ray lasers with high peak powers. An approach was presented for rendering short-pulse x-ray lasers that should easily be extrapolated to any collisionally pumped x-ray laser system. Neonlike yttrium x-ray laser, which operated at a wavelength of 15.5 nm, was selected for the experiments. The significance of multiple-pulse irradiation in optimizing the gain region was discussed, together with the benefits of a traveling-wave pump for maximizing the output power and reducing the pulse width. The experiments were modeled employing a combined computational method including two-dimensional simulation with LASNEX, a two-dimensional kinetics and gain simulation with XRASER, and a three-dimensional x-ray laser propagation with CASER.
