Abstract

Theoretical-computational studies of table-Top laser-driven nuclear fusion of high-energy (up to 15 MeV) deuterons with 7Li, 6Li, and D nuclei demonstrate the attainment of high fusion yields within a source-target reaction design. This constitutes a source of Coulomb-exploding deuterium nanodroplets driven by an ultraintense femtosecond near-infrared laser and a solid hollow cylindrical target containing the second element. The source-target reaction design attains the highest table-Top fusion efficiencies (up to 4 × 109 J-1 per laser pulse) obtained to date. The highest conversion efficiency of laser energy to nuclear energy (10-2-10-3/ for table-Top DD fusion attained in the source-target design is comparable to that for DT fusion currently accomplished for 'big science' inertial fusion setups.
