Kinetics experiments on neon-like X-ray lasers

摘要

Recent results from experiments with neon-like x-ray lasers are discussed. Lasing in an Ag amplifier is demonstrated. The strong J=2-1 transitions are shown to have large gains. A J=0-1 transition at 81.57 A is the shortest lasing transition yet observed in neon-like ions. A quasi-cw laser is demonstrated in experiments with germanium amplifiers. A substantial difference is shown to exist between the spectroscopy of lasers produced in exploding foils and slab targets. Experiments with over-ionized germanium lasers are also discussed.
