Experimental investigation of double-pass amplification of an x-ray laser in neonlike germanium.

Experimental investigations of double-pass amplification of an x-ray laser in Ne-like germanium were carried out at the Shengguang laser facility (of the High Power Laser and Physics Laboratory, Shanghai, China). In these experiments a molybdenum-silicon multilayer mirror was used at normal incidence, and a flat-field grating spectrograph was used to measure the intensities of the laser lines
