A high power subpicosecond laser (10/sup 16/ W/cm/sup 2/, 7 mJ, 400 fs FWHM) has been used to create solid density plasmas in a number of target materials, including carbon and copper. Plasma soft x-ray spectra indicate temperatures of 100--200 eV. Resulting soft x-ray bursts from a copper target are measured at the limit of a streak camera's resolution to be at most 20 psec in duration, the shortest burst of x-rays measured to date. Preliminary evidence is presented of novel ''inverted'' reflectivities of these solid density plasmas at the highest laser power densities.
