Abstract

This paper discusses recent progress in LLNL's high resolution XUV spectroscopy efforts with x-ray laser plasmas. We describe the instrumentation used, and we present preliminary time-resolved data on the spectral profiles of several XUV (extreme ultraviolet) lines from Ne- like Se and Ne-like Y x-ray lasers which have been obtained with instrumental resolutions ((lambda) /(Delta) (lambda) ) of approximately 10,000. The Se data indicates that the 206.4 angstroms J equals 2 - 1 laser line narrows below the expected 400 eV Doppler width (35 m angstroms) when amplified through approximately 6 gain lengths, while the Y data shows no evidence of the J equals 0 - 1 laser predicted to be nearly resonant with the J equals 2 - 1 laser at 154.9 angstroms.
