Abstract

We present a comparative study of the x-ray emission produced by laser plasma sources in short ((tau) _L equals 0.6 ps) and long ((tau) _L equals 0.6 ns) pulse regimes for copper and tantalum targets. The experiments at (tau) _L equals 0.6 ps show that the x-ray conversion efficiency (eta) is still increasing with laser intensity between 2 X 10¹⁵ W/cm² and 5 X 10¹⁶ W/cm² for both sub-keV (0.1 - 0.75 keV) and keV (0.75 - 2 keV) ranges. In addition, we found that the optimum values (eta) at (tau) _L equals 0.6 ps are at least 2 - 4 times lower than those at (tau) _L equals 0.6 ns.
