Narrow-band hard-x-ray lasing — •Chunhai Lyu, Stefano M. Cavaletto, Zoltán Harman, and Christoph H. Keitel — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany

We put forward a scheme to obtain a narrow-band x-ray laser by K-shell photoionization of Li-like highly charged ions in a laser-generated plasma. Ions of Ne, Ar, Kr and Xe have been examined. Numerical simulations show that the intensities of such x-ray lasers saturate within a few millimeters with transform-limited profiles. Such temporal coherences provide x-ray laser bandwidths up to three orders of magnitude narrower compared to the future seeded-XFEL sources in the hard x-ray regime.
