Spatiotemporal characterization of laser filaments in noble gases — •Christoph Jusko¹, Lana Neoricic², Shiyang Zhong², Miguel Miranda², Cord Arnold², and Milutin Kovacev¹ — ¹Institut für Quantenoptik, Leibniz Universität Hannover, Welfengarten 1, 30167 Hannover, Deutschland — ²Division of Atomic Physics, Lund University, Professorsgatan 1, 223 63 Lund, Schweden

Laser filaments in noble gases show highly nonlinear temporal and spatial dynamics along the propagation direction, e.g. leading to high peak intensities, spectral broadening and interesting effects like self-shortening of femtosecond laser pulses. We present an experimental approach for a comprehensive, propagation-position-dependent study of the temporal as well as the spatial filament dynamics taking place in argon. Later, insights about the dynamics could support pump-probe studies on noble gas filaments in order to detect Kramers-Henneberger atoms.
