Abstract

The laser-produced plasma channel may be a promising means of producing an efficient compact soft-x-ray laser. The plasma parameters in such a plasma waveguide are calculated with a self-similar model. It is shown that nonequilibrium underdense plasmas and candidate ions for recombination laser schemes can be obtained. As an example, the laser gains of the transition $1s3d–1s2p$ of He-like N ions are calculated for given pumping energies and initial gas densities.
