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 (λ/Δλ) of ∼10,000. The Se data indicates that the 206.4 Å J = 2-1 laser line narrows below the expected 400 eV Doppler width (35 mÅ) when amplified through ∼6 gain lengths, while the Y data shows no evidence of the J = 0-1 laser predicted to be nearly resonant with the J = 2-1 laser at 154.9 Å.
