Paper Abstract

Study of the spectrally and temporally resolved emission of x-rays from laser-irradiated targets can provide information on the absorption of laser energy and its transport in the target, and on the general hydrodynamics of imploding target shells. In this paper we describe the 14 channel streak spectrometer in use at the Laboratory for Laser Energetics, University of Rochester and relate its use in investigating laser-matter interaction at λ=0.35 μm and 1.054 μm. In addition to a description of the 14 channel, CsI-Au bifurcated photocathode device, we describe its novel use in providing an absolute laser (λ=0.35 μm) fiducial from light scattered specularly from planar targets; its use in symmetrically imploded targets (λ=1.054 μm); its use in investigations of thermal transport; and a novel use of the differentially comparing densitometer to remove film characteristics.
