Abstract Experimental results are reported of investigations of the optical properties of the plasma produced when an AI2O3 target is irradiated in vacuum by a high-power neodymiunr-glass laser system. It is shown that a number of 0 VIII and 0 VII ion levels with principal quantum numbers n = 2, 3, 4 are inversely populated. The gain at the wavelength λ ≃ 29 nm (4 → 3 transition, O VIII) under the experimental conditions is of the order of 0.01 cm-1. For the heliumlike ions O VII, in a transition with the same principal quantum numbers (ls4p1P1 → ls3s1S0, λ ≃ 36.9 nm), the gain is of the order of ∼ 10-2–10-1 cm-1, depending on the electron density.
