Experiments on X-ray laser photo-pumping

摘要

The first set of experiments described in this paper involves the determination of pump line intensities from laser-produced plasmas. X-ray intensities (in photons per mode) emitted by resonance lines of neon-like ions are measured at a fixed pump laser intensity of 4 × 10~(13) W/cm~2 for a range of medium-Z materials.rnIn a second set of experiments the feasibility of photo-resonant pumping in a geometry of two parallel line foci is demonstrated.
