Abstract : The amplification of x radiation by stimulated emission appears to be nearing the point of being experimentally feasible. This report analyzes the theoretical foundations for an x-ray laser by means of a generalized rate equation approach and determines the general requirements to be placed on the pumping rate, its rate of rise, and on excited-state lifetimes. These requirements give a basis for a selection and optimization of promising excitation (pumping) techniques and possible lasing media. In addition, most of the previous literature relevant to x-ray lasers have been reviewed and evaluated to assess its likely future application in the development of a realistic x-ray laser. (Author)
