Abstract

The spatial and temporal behaviour of the X-ray gain in laser-produced plasmas is investigated theoretically. Hydrodynamical 1–D simulations of plasma heating and expansion for different laser parameters are combined with calculations of the corresponding density distributions for the ionic states in the plasma. The interesting energy level populations in hydrogen-like ions are found with radiation reabsorption taken into account. Results will be presented for cylindrical C and Al targets for the 3→2 (C) and 4→3 (C, Al) transitions. It is shown that the reabsorption of the Lα-line reduces the value of the gain for the 3→2 transition and modifies its spatial and temporal distribution.
