Abstract

In order to study the ion acceleration in ultra-intense laser plasma interactions, we measured neutron spectra from the D-D ion nuclear reactions in the target. 50-100TW/0.5-1 ps laser light irradiated obliquely dueterated plastic solid targets with different laser polarizations and intensities. Comparing the neutron spectra with the 3D Monte-Carlo simulation indicates ion acceleration in the near target normal direction at any polarization and increases in the ion energy with laser intensity.
