Abstract

The interaction of high intensity femtosecond laser pulses (1019 W/cm2) with matter is a topic of current interest. Due to the short laser pulse duration, this leads to rapid ionization before a considerable expansion and it becomes possible to heat solids to mean electron energies of several keV at almost constant ion density. Plasmas with high electron densities and short scale lengths are created with relatively moderate laser energies. Much work has concentrated on the generation and characterization of ultrashort X-ray bursts,1 investigations of the plasma dynamics2–4 and on transport properties of dense plasmas through reflectivity measurements.5–8 Production of matter in such a state allows the study of basic plasma physics in regimes relevant to astrophysics, atomic physics, or in strongly correlated plasmas.9
