X-Ray Emission from Laser-Produced Plasmas.
Ten to forty Angstrom x-ray emission from laser -produced plasmas was studied in order to determine pertinent plasma parameters, study plasma-emission characteristics under varying laser/target conditions, and in order to generate characterization data on Layered Synthetic Microstructure (LSMs). Plasma temperatures were determined and compared with temperatures obtained by other workers. The calculated temperatures were consistent, but precise temperature determination was not possible because density information was not calculable. The emission characteristics showed surprisingly little dependence on target parameters or laser intensity. The integrated reflectivity and line width of the LSMs, as determined from this research, matched values predicted from theoretical computations. In addition, the focusing ability of LSMs was demonstrated.
