M. Borghesi et al., CHARACTERIZATION OF LASER PLASMAS FOR INTERACTION STUDIES - PROGRESS IN TIME-RESOLVED DENSITY MAPPING, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 54(6), 1996, pp. 6769-6773
Time-resolved probe interferometry was used to obtain complete density
mapping of laser produced plasmas. The plasma was produced by symmetr
ical irradiation of thin targets, to be used for short pulse delayed i
nteraction experiments. The progress in the plasma characterization du
e to the use of a picosecond pulse probe is reported, and the relative
merits of different target designs are also discussed. The two-dimens
ional density maps obtained appear to be in substantial agreement with
two-dimensional hydrodynamic code predictions.
