Laser Diagnostics of Metallic Plasmas.
Abstract
The major objectives of this research project were to study the X-ray emission and dynamical behavior of exploded aluminum wire plasmas when subjected to intense CO2 laser radiation. The laser system based on Lumonics 601 TEA laser was optimized to produce a diffraction limited spot size (diameter 125 microns) yielding a focused intensity of 10 to the 12th power w/sqcm. The principal X-ray diagnostics consisted of two foil measurements using filtered photomultiplier detectors. These measurements were augmented by a variety of electrical and optical diagnostics to determine the time evolution of the exploding wire and the effects of the laser irradiation. Interaction experiments were performed with a radial, one sided illumination at the plasma midplane. The data obtained in these experiments is discussed and analyzed in the report. (Author)
