Spectra produced by high-intensity, subpicosecond KrF laser pulses in a preformed carbon plasma are measured in the 10 - 700 A-spectral range. These spectra differ from those produced on the surface of a solid without a preplasma. The main change in the spectra is explained by the field ionization of atoms and ions of the preplasma as a dominant mechanism of interaction.
