Abstract

Laser based x-ray sources at h(upsilon) approximately equals 0.9 - 1.2 keV (Fe to Cu L-shell) developed for applications are studied from the point of view of x-ray emission spectra. X-ray spectra obtained with different laser intensities and wavelengths using Nd and KrF lasers are described. Results are qualitatively compared with the predictions of simple analytical models for plasma temperature Te and average ionization Z*. When using KrF lasers it is possible to introduce a He atmosphere in the interaction chamber to reduce the debris problem. X-ray spectra at different He pressures were recorded and x-ray L-shell emission of Fe and Cu were shown to be largely independent of the pressure.
