Abstract

We consider nonlinear interaction of superpower laser pulses of relativistic intensities with nanolayers and solid-plasma-targets towards the production of high energy-density electron bunches along with nuclear radiation (hard % γ-quanta and positron fluxes). It is shown that petawatt lasers are capable of producing via two-target scheme high density field free electron/positron bunches and substantial amounts of γ-quanta with energies up to 200 MeV. For actual supershort and tightly focused--strongly nonplane ultrarelativistic laser pulses of linear and circular polarizations 3D3V problem is solved via numerical simulations.
