Recombination x-ray lasers of heliumlike nitrogen ions in a plasma waveguide

摘要

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. (C) 1997 Optical Society of America.
