Paper Abstract

The development of keV X-ray lasers based on inner-shell atomic transitions requires extremely fast energy deposition on a target in order to effectively compete with the inherently fast (0.1 - 20 fs) atomic decay processes. The duration of ultrahigh peak power laser systems is now reaching this timescale. In principle, these systems can be used to produce sufficient duration and energy X-rays or electrons for pumping inner-shell transitions. In this paper X-ray laser schemes are described in which the Coster-Kronig Auger-process is the dominant lower level decay mechanism. Such systems have inherently short lower level lifetimes and it is shown that under certain conditions they can be inverted with excitation by energetic electrons as well as X-rays. They are therefore relatively immune to secondary electron ionization.
