Resonant photon pumping mechanisms for a plasma x-ray laser

摘要

A lasing system for lasing at x-ray wavelengths. In one embodiment, a neoike sulfur ion S.sup.6+ plasma is caused to radiate on its 3d→ 2p transition to pump a lithium-like neon Ne.sup.7+ plasma to obtain x- ray lasing. In a second embodiment, a lithium-like silicon S. sub.i.sup.11+ ion plasma is caused to radiate on the 3d→2p transition to pump lithium-like magnesium Mg.sup.9+ plasma to obtain x- ray lasing.
