Abstract

A SiO₂ aerogel with absorbed deuterium is suggested as a target for the fusion reaction d + d yields He³ + n by a super-intense ultra-short laser pulse. The multiple inner ionization of oxygen and silicon atoms in the fibers of this fractal aerogel takes place in super-intense laser field. The Coulomb explosion of the deuterated aerogel skeleton propels deuterons up to kinetic energies of ten keV and higher. The neutron yield is estimated up to 10⁵ neutrons per laser pulse during approximately 500 ps if the peak intensity is 10¹⁸ W/cm² and pulse duration is 35 fs.
