Abstract
We report time-resolved spectroscopic analysis of laser-produced plasm a x-ray sources. Plasmas produced by a 400-fs 1-TW tabletop laser are characterized with a transmission grating spectrometer coupled to a so ft-x-ray streak camera. Soft-x-ray radiation in the 1-6-nm range with durations of 2-7 ps is observed for copper and tantalum plasmas. The e ffect of incident laser energy on the x-ray pulse duration is also inv estigated.
