Laser-Plasma Interaction in a Strong External Magnetic Field — •Ralph Jung1, Thomas Fischer1, Helmut Kempkens1, Georg Pretzler1, Oswald Willi1, Kay-Uwe Amthor2, Laszlo Veisz2, Wolfgang Ziegler2, and Roland Sauerbrey2 — 1Institut für Laser- und Plasmaphysik, Heinrich-Heine-Universität Düsseldorf, Universitätsstr. 1, 40225 Düsseldorf — 2Institut für Optik und Quantenelektronik, Friedrich-Schiller-Universität Jena
The plasma formation and the expansion of the plasma channel produced by the interaction of intense ultrashort laser pulses (I>1017 W/cm2, 100 fs) with gaseous targets have been studied in a strong external magnetic field (8 T). The diagnostics included optical probing with a delayed frequency doubled pulse as well as optical spectroscopy of the backward and forward scattered laser radiation.
First results of the observations with and without the external magnetic field and a preliminary interpretation of the results will be presented.
