摘要：

Oblique incidence of a p-polarized laser beam on a fully ionized plasma with a low density plasma corona is investigated numerically by particle-in-cell and Vlasov simulations in two dimensions. A single narrow self-focused current jet of energetic electrons is observed to be projected into the corona nearly normal to the target. Magnetic fields enhance the penetration depth of the electrons into the corona. A scaling law for the angle of the ejected electrons with incident laser intensity is given.
