Abstract
New experimental results on laser irradiation (I
1014 W/cm2,
= 1.053 
m) of low-density fibrous agar are
presented. X-ray spectrometers with spherically bent mica crystals were used
for measuring with high spectral resolution the line spectra of multicharge
ions. Detailed analysis of the measured spectra made it possible to
determine the temperature of electrons and ions in hot plasma created in
laser irradiated low-density samples in dependence on average material
density and average intensity within a focal spot. Significant difference
between ion and electron temperatures is found for the whole range of
experimental conditions.
