Paper Abstract

The development of lasers operating in the wavelength range 30-200A using laser produced plasmas as lasant has been widely demonstrated. Recombination into hydrogen and lithium-like ions leads to population inversion and gain in expanding and cooling plasmas. The general principles of such devices will be discussed, and experimental demonstration of their operation considered. At present the most flexible device uses small plasmas generated from a restricted target-fibre or stripe. In principle such systems allow scaleability to below the water window at 44A from the present demonstrations at 50-200A. The detailed design of such devices involving target geometry and composition, variation and pump pulse characteristics, will be discussed.
