Femtosecond-pulse-driven electron-excited extreme-ultraviolet lasers in Be-like ions.
A suggestion for the generation of extreme-ultraviolet (XUV) laser radiation based on tunneling ionization and subsequent electron excitation of Deltan not equal 0 transitions is described. The favorable scaling of the required intensity of the pump laser with the output XUV wavelength is compared with that exhibited by XUV lasers ased on Deltan = 0 transitions. Calculations for Be-like Ne predict signif icant gain at 14.1 nm.
