Characterization of fast electrons accelerated into matter by laser-solid interaction — •Nico Potzkai, Bastian Hagmeister, and Georg Pretzler — Institut für Laser- und Plasmaphysik, Heinrich-Heine-Universität Düsseldorf

Intense laser pulses create plasma on solid surfaces and accelerate electrons into the vacuum as well as into the target. We investigated the latter electrons concerning numbers and energy. Sub 10-fs-laser pulses on different bilayer targets did induce the plasma. The characteristic x-ray line emissions of the two materials were used to quantify the electron population traveling though the material. Our experimental results have been compared with PIC simulations and yield information of details of the laser-surface interaction.
