Two-stage compression of a plasma of multicharged ions created in a low-inductive high-current capillary Z-discharge as a method for pumping the active medium of short-wave lasers

The possibility of stepwise formation of the active laser medium on a plasma of multicharged ions is shown based on the numerical simulation results. Practically, such compression can be carried out with a high-voltage generator, storage and forming lines. It is presented that at conditions I m ≥ 200kA in stepwise pumping mode, it is possible to obtain Xe-plasma parameters with an electron temperature Te>400 eV and a concentration Ne>10 20 cm −3 . Such plasma is a good medium for amplification of spontaneous radiation at several transitions in the spectral region λ≈10 nm in a Xe-plasma of Ni-like ions: it can provide a gain at the transitions g+~ ∼ 1-2 cm −1 .
