The dynamics and nonequilibrium ionic composition of a highly ionized plasma сreated by interaction of a high-power laser-radiation pulse with a cylindrical plasma target

Based on the results of numerical simulation using a nonstationary one-dimensional two-temperature radiation hydrodynamic model, the main physical processes have been analyzed that govern the formation of cylindrical plasma bunches with a nonequilibrium ionic composition containing ions of high ionization multiplicity under laser intensities of $Q_L\le$ 10$^{14}$ W/cm$^2$ and energies of $E_L\sim$ 10 J/cm. The work is aimed at the creation of active media for lasers generating in the extreme ultraviolet and soft X-ray spectral ranges.
