Notes:
Laser-target interaction was studied to make an efficient soft-x-ray source with a table-top laser system. A 1-J, 20-ns ruby laser was focused on various planar targets (Z=6 to 82). The laser power intensity on the targets was about 1011–1012 W/cm2. Spectra (2–35 nm) and intensities of soft x-ray radiation from target plasma were measured by using a 2-m grazing incidence spectrometer and a x-ray diode. Even at this low laser power intensity, high-energy radiation of 0.5–3 keV was obtained. Spectra from low-Z materials show strong line radiations over a weak continuum and those from high-Z materials consist of a continuum predominantly. The target Z-number dependence of the intensity of 0.5–3-keV radiation has a periodic structure and relates to atomic shell structures. In this experiment the maximum x-ray conversion efficiency was obtained from a 22Ti target.
