The population of autoionizing doubly excited states in the laser fields is proven and a possible connection to the well-known dielectronic recombination processes is discussed. The fundamental process of tunnel ionization in strong laser fields is subject of investigation in a pump-probe experiment with ultrashort laser pulses. A coherent superposition of electronic states in singly charged argon ions is created within the first, and subsequently tunnel-ionized with the second pulse. This gives access to state-selective information about the tunneling process and allows to test common models. Moreover, the ionization of krypton and argon at different wavelengths is studied, from the multiphoton to the tunneling regime. The wavelength-dependent investigations are furthermore extended to molecular hydrogen. In addition to ionization, this system might undergo different dissociative processes. Channel-selective electron momentum distributions are presented and compared to each other. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aAtoms 606 $aPhysics 606 $aSpectrum analysis 606 $aMicroscopy 606 $aAtoms and Molecules in Strong Fields, Laser Matter Interaction$3https://scigraph.springernature.com/ontologies/product-market-codes/P24025 606 $aSpectroscopy and Microscopy$3https://scigraph.springernature.com/ontologies/product-market-codes/P31090 615 0$aAtoms. 615 0$aPhysics. 615 0$aSpectrum analysis. 615 0$aMicroscopy. 615 14$aAtoms and Molecules in Strong Fields, Laser Matter Interaction. 615 24$aSpectroscopy and Microscopy. 676 $a546.26423 700 $aFechner$b Lutz$4aut$4http://id.loc.gov/vocabulary/relators/aut$0805142 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910254634003321 996 $aHigh-Resolution Experiments on Strong-Field Ionization of Atoms and Molecules$91807650 997 $aUNINA
