Beschreibungen/Notizen

• Observations of amplified spontaneous emission at soft X-ray wavelengths are reported. An optical laser ionized thin foils of selenium to produce a population inversion of the 2p(5)3p and 2p(5)3s levels of the neonlike ion. Using three time-resolved, spectroscopic measurements, gain-length products up to 6.5 and gain coefficients of 5.5 + or - 1.0/cm were demonstrated for the J = 2 to 1 lines at 206.3 and 209.6 A. Considerable amplification for the same transitions in yttrium at 155.0 and 157.1 A was also observed.
