Abstract
Multistage, e-beam-pumped, 100 J-class KrF laser
installation “GARPUN” is described with the
emphases to high-power laser beam control and target irradiation
experiments. The ablation pressures in the megabar range
were measured and hydrodynamic flow was investigated both
experimentally and by numerical simulations for laser intensities
up to 5×1012 W/cm2, pulse duration
of 100 ns, and focal spot diameter 150 μm. Graphite-diamond
phase transformation under laser loading was observed by
dynamic and Raman scattering methods. Some approaches to
the fast ignition inertial confinement fusion, using the
simultaneous amplification of long and short laser pulses
in KrF drivers, are considered.
