Collimated electron jets by intense laser-beam-plasma surface interaction under oblique incidence

Oblique incidence of a p-polarized laser beam on a fully ionized plasma wit h a low density plasma corona is investigated numerically by particle-in-ce ll and Vlasov simulations in two dimensions. A single narrow self-focused c urrent jet of energetic electrons is observed to be projected into the coro na nearly normal to the target. Magnetic fields enhance the penetration dep th of the electrons into the corona. A scaling law for the angle of the eje cted electrons with incident laser intensity is given.
