Collisionally pumped soft x-ray lasers now operate over a wavelength range extending from 35 to 300 A. These well-characterized sources have high peak brightness (GeV blackbody temperature) and narrow bandwidth making them ideal for x-ray imaging and interferometry. We will describe experiments which have used the yttrium neon-like x-ray laser operating at 155 A to probe plasmas at electron densities exceeding 4[times]10[sup 21] cm[sup [minus]3]. The short pulse duration of this x-ray laser ([similar to]150 ps) has made it possible to image directly driven thin foils with 1--2 [mu]m spatial resolution. Advances in multilayer mirrors and beam splitters have now also made it possible to develop x-ray laser interferometers. We will describe initial experiments to probe plasmas relevant to ICF using x-ray laser interferometry. The progress in the development of short pulse x-ray lasers ([similar to]30 ps) which are ultimately necessary to extend x-ray laser diagnostic techniques to higher densities will also be presented.
