Micro-Scale Fusion in Dense Nanowire Arrays Irradiated by Femtosecond Laser Pulses of Relativistic Intensity

Irradiation of deuterated nanowire arrays with femtosecond pulses of relativistic intensity creates ultra-high energy density plasmas where deuterons are accelerated to MeV energies, efficiently driving D-D fusion reactions with record neutron yield for joule-level lasers.
