Abstract

We report observations of amplified spontaneous emission at soft x-ray wavelengths. An optical laser ionized thin foils of selenium to produce a population inversion of the 2p53p and 2p53s levels of the neonlike ion. Using three time-resolved, spectroscopic measurements we demonstrated gain-length products up to 6.5 and gain coefficients of 5.5±1.0 cm-1 for the J=2 to 1 lines at 206.3 and 209.6. We also observed considerable amplification for the same transitions in yttrium at 155.0 and 157.1.
