Spectroscopic Analysis of the Density and Temperature Gradients in the Laser-Heated Gas Jet

摘要

We have performed an analysis of the x-ray spectra produced by a 1.0TW, lambda/sub L/-0.53 mu m laser-irradiated gas jet. Plasmas produced by ionization of neon, argon and N sub 2 + SF sub 6 gases were included in those measurements. Plasma electron density and temperature gradients were obtained by comparison of measured spectra with those produced by computer modeling. Density gradients were also obtained using laser interferometry. The limitations of this technique for plasma diagnosis will be discussed. (ERA citation 07:013419)
