Volumetric creation of ultra-high-energy-density plasma by irradiation of ordered nanowire arrays
Creating appreciable volumes of Ultra-High-Energy Density (UHED) matter in the laboratory is a challenge. Recent developments in the fabrication of vertically aligned nanowire array targets, in coordination with ultra-high-contrast femtosecond laser pulses focused to relativistic intensity, have opened the door to creating UHED matter using compact laser facilities with laser pulses of ~ 0.6 J. These high aspect ratio, vertically aligned nanostructure targets allow the laser energy to penetrate deep into the near-solid density material and heat plasmas to keV temperatures, generating Gbar pressures ...
