Abstract

The experimental measurements of soft x-ray laser spectra with high time-resolution (approximately 50 ps) are reported. The Ge-slab targets were irradiated by line focused laser beam with irradiance of 1.2 X 10¹³ w/cm². The laser pulse width is 1 ns. Using a flat field grating spectrometer and a soft x-ray streak camera, we have obtained temporal characters of four soft x-ray lasing lines with wavelengths of 19.6, 23.2, 23.6, and 28.6 nm emitted from the 3p - 3s transitions in Ne-like Ge plasma. The results indicate that these lines did not appear at the same time and their duration was about 0.83 ns.
