Abstract:

We present results from a 1-D plasma dynamics calculation, describing the evolution of strongly heated material in the vicinity of a solid-vacuum interface. We find that the radiation emitted by the hot material in the range hv kt sub e, where T sub e is the initial peak plasma temperature, comes primarily from the region of the original step function interface. This emission is dominated by recombination radiation. The emitted radiation pulse is extremely short the cooling at the interface is dominated by expansion. The interaction of energetic subpicosecond laser pulses with solid matter is of great current interest because of the possibility of producing ultrashort x-ray pulses from the resulting plasmas 1, or for the study of the properties of the novel, highly excited material.
