Abstract

Current x-ray lasers operate in the 35 to 500 angstroms wavelength regimes with 21.5 angstroms being the limit for the successful collisional excitation approach using Nickel-like ions. In this paper, we discuss an x-ray laser scheme in the 5 to 15 angstroms regime. The scheme uses an ultra-short (100 fsec FWHM) intense (10¹⁷ Watts/cm²) laser pulse to produce a hot plasma at a laser line focus. This plasma serves as an x-ray source that photo- ionizes the K shell of a nearby concentration of lasant atoms. This produces a population inversion, and resulting positive gain for an allowed 2p-1s radiative transition in the singly charged ion.
