Abstract

Dynamical behaviour of picosecond soft x-rays generated from laser-produced plasmas were studied both theoretically and experimentally. A grazing incident suctrometer with a flat field focal plane is developed and time resolved spectra near 100 A are obtained by using a newly designed XUV streak camera with 10 ps time resolutions. Temporal changes of intensities of soft x-rays from laser produced plasmas is investigated for various targets. Decay times are about 100 ps and decrease as targets are changed from low Z to high Z materials. Computationally, temporal changes of x-ray intensities is predicted in the framework of the simplified model. A qualitative agreement between experimental and computational results is obtained.
