The increase in the XUV mass absorption coefficient of liquid aluminium, produced by high-power-laser shock-compression, is measured using XUV laser radiography. At a photon energy of 63 eV a change in the mass absorption coefficient by up to a facto

Progress of a four-wave sum difference frequency generation scheme to convert coherent soft X-ray radiation to shorter wavelengths, using a plasma medium is discussed. Results are presented from a preliminary experiment, involving the Ne-like Ni XRL

The characteristics of an extreme-ultraviolet (XUV) continuum light source and its application to a dual-laser plasma (DLP) photoabsorption experiment are described. The continuum emitting plasma was formed by focusing a 7 ps, 248 nm, 15 mJ laser pul

A ∼3 ps travelling wave chirped pulse amplified pulse at 6×10 14 W cm −2 superimposed on ∼300 ps background pulses is shown to be an efficient method to pump transient collisional excitation X-ray lasers in both Ni-like and Ne-like ions. Measu

We report a systematic study of double pulse pumping of the Ni-like Sm x-ray laser at 73 Angstrom, currently the shortest wavelength saturated x-ray laser. It is found that the Sm x-ray laser output can change by orders of magnitude when the intensit

Driven by a double 75 ps pulse with 2.2 ns separation, saturated operation of nickel-like Ag, In, Sn, and Sm X-ray lasers have been demonstrated with only 75 J drive energy on target. The variation of X-ray laser output with target length is found to

Summary form only given. High efficiency of the transient collisional excitation (TCE) pumping of X-ray lasers has been demonstrated recently. TCE relies an the rapid increase of the electron temperature in a preformed plasma irradiated with a short
