Influence of the laser waveform of near single-cycle laser pulses on the dissociative ionization of N2O — •Christian Jendrzejewski1,2, Matthias Kübel1,2, and Matthias Kling1,2 — 1Ludwig-Maximilians-Universität München, Garching, Germany — 2Max-Planck-Institut für Quantenoptik, Garching, Germany
Within the past few years, the development of near-single cycle laser pulses allowed for various studies on electron dynamics in the femto- and attosecond time scale which are fundamental for chemical reactions. In order to investigate the ionization behavior of triatomic molecules in such laser fields laughing gas (N2O) is used as a model system. Thereby, the focus lies on the non sequential double ionization (NSDI) as it is highly important for correlated electron processes. The ionization products of the N2O molecule are temporally and spacially resolved within a reaction microscope. As such photoionization processes are strongly dependent on the laser waveform of the pulse, especially on the carrier-envelope phase (CEP), the CEP is detected for each laser pulse. Combining these two methods, strong dependencies of the ionization yield on the CEP and polarization of the laser pulse are observed.
