Wavelength and intensity dependent fragmentation of H2+ in the mid-infrared — •Wustelt P.1,2, Möller M.1,2, Rathje T.1,2, Sayler A.M.1,2, and Paulus G.G.1,21Institute of Optics and Quantum Electronics, Friedrich Schiller University Jena, Germany — 2Helmholtz Institute Jena, Germany

The wavelength and intensity dependent ultra-short laser-induced ionization and dissociation of an H2+ molecular ion beam target is measured at mid-infrared wavelength between 0.8 and 2.2 µm and at intensities up to 1016 W/cm2. A three-dimensional coincidence imaging system allows kinematically complete coincidence measurements of both fragmentation channels and enables an unprecedented look into laser-driven fragmentation dynamics of the simplest molecule in strong mid-infrared laser fields.
