Abstract
Implosions of large-diameter thin-walled laser fusion targets driven by UV (351-nm) light at low intensities (<2 × 1014 W/cm2) are of interest for several reasons: The laser–target interaction is dominated by inverse bremsstrahlung absorption, optimizing the ablation pressure, while production of hot electrons by parametric processes is minimized. The low-mass shells are accelerated to high velocities leading to high core temperatures and high neutron yields. The high neutron yields permit sensitive measurement of fuel and shell areal densities.
