Abstract

We report on the observation of high energy ions with energies up to 1 MeV accelerated pondermotively by a relativistically self-focused intense 5 TW, 400 fs laser pulse in a supersonic He gas jet on the distance of a laser spot size. Probing interferometry was used to observe on-axis electron-ion cavitation followed by the plasma expansion with a high radial velocity of approximately 3.8·10⁸ cm/s. Using the nuclear track detector CR-39, we confirmed that the ions are preferentially accelerated in the radial direction and the total energy in high energy ions is about 1% of the laser energy. Developed kinetic modeling provides a reasonable description of a plasma channel formation and ion acceleration.
