Saturation and Kinetic Issues for Optical-Field-Ionized Plasma X-Ray Lasers,
Abstract
Lasing between excited states and the ground state following optical-field ionization is studied. Saturation of an x-ray laser when the lower lasing level is a ground state of a hydrogen-like or lithium-like ion is discussed. Efficiencies of 0.00001 to 0.00001 are calculated for the 3d5/2 - 2p3/2 transition at 98 A in Li-like neon. The assumption that the fine-structure levels are populated according to their statistical weights is shown to be justified through comparisons with calculations using a detailed atomic model. The effect of saturation by a given fine-structure transition on the populations of the fine-structure levels is analyzed. Optical-field ionization by a high-intensity/short-pulse ultraviolet laser allows the possibility of x-ray lasing between excited states of an ion and the ground state.
