We have conducted experiments to determine the effects of target thickness on the time history and spectra from short pulse laser produced plasmas. A reduced contribution to conduction cooling was achieved by using thin targets. The experiment was do

Time- and two-dimensional spatially-resolved monochromatic imaging is performed on Ne-like germanium laser-produced line plasmas to study the behaviour of the inhomogeneities along the line created by a nonuniform irradiation. The imaging is done at

The K -shell emission from porous aluminum targets is used to infer the density and temperature of plasmas created with 800 and 400 nm, 140 fsec laser light. The laser beam is focused to a minimum spot size of 5 μm with 800 nm light and 3 μm with 4
