Abstract
Quasiresonant photoexcitation and nonresonant photoionization of He-li ke ions in a two-component laser-produced plasma are demonstrated in t he x-ray range. The pumping source is the x-ray emission of a high-Z p lasma which modifies the populations of the excited states of an alumi num He-like plasma. Fluorescence of the 1s2p-1s(2) line at 7.757 Angst rom has been measured by time-resolved and time-integrated spectral me asurements of the two plasma emissions. Photoionization results compar e favorably with radiative transfer simulations which calculate the He -like 1s2p-1s(2) line transfer in the photopumped aluminum plasma.
