Abstract
In this paper, the results of studies on soft X-ray population inversion by the resonant photoexcitation process are presented. The experimental studies in highly ionized multicomponent plasmas produced by high power glass laser indicate large population inversion densities at wavelengths\lsim 130Å. Intensity inversions of resonance lines from then = 3andn = 4levels of Mg11+ions at electron densities as high as 1020cm-3have been observed, indicating that gains of\sim 5-10cm-1have been achieved. These results and other photon-assisted soft X-ray population inversion schemes in inhomogeneous plasmas are discussed.Keywords
