Kollimierte energetische Elektronen von laser-bestrahlten Plasmaoberflächen — •Hartmut Ruhl1 and Yasuhiko Sentoku21Theoretische Quantenelektronik, TU Darmstadt, Hochschulstraße 4A, 64289 Darmstadt, Germany — 2Institute of Laser Engineering, Osaka University, 2-6 Yamada-oka, Suita, 565 Osaka, Japan

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.
