Time-Resolved X-Ray Spectroscopy of Laser-Produced Plasmas

Abstract

X-ray emission spectra, produced by irradiation of neon-filled aluminum-coated glass microballoon and plane aluminum targets, with 100-ps Nd-glass laser pulses, have been time resolved with an x-ray streak camera. The time evolution of the $\mathrm{Ne}\ifmmode\times\else\texttimes\fi{}L\ensuremath{\alpha}$ and Si xiii $1^{1}S_{0}\ensuremath{-}3^{1}P_{1}$ linewidths has been recorded. The implosion delay time of microballoon targets and the emission histories of the Al xiii $1^{1}S_{0}\ensuremath{-}2^{1}P_{1}$ line and its satellites from plane targets have been measured.
