1. Non-linear mid-infrared laser techniques for combustion diagnostics
Sammanfattning : .... LÄS MER
2. Non-linear attosecond physics at 100 eV
Sammanfattning : Non-linear interactions between light and matter have nowadays a broad range of applications. They are used for frequency doubling in simple laser pointers as well as for a variety of purposes in complex laser systems like the one presented in this thesis. LÄS MER
3. Theoretical perspectives on ultrafast and non-linear spectroscopy
Sammanfattning : In this thesis we discuss a theoretical description of ultrafast and non-linear spectroscopy. Due to the high intensities and ultrashort pulse durations involved in such experiments, it is necessary to use an explicitly time-dependent formalism. LÄS MER
4. Non-Linear Spatio-Temporal Dynamics of Optical Beams and Pulses in Kerr and Ionizable Media
Sammanfattning : The present thesis includes results of several investigations concerning the propagation of optical pulses in optical fibers and spatio-temporal beams in optical Kerr media and ionizable media. Both numerical and analytical methods play an important role in the investigations. LÄS MER
5. Non-linear Spectroscopy of Conical Intersections
Sammanfattning : Conical Intersections (CIs) in a molecule originate from the breakdown of the Born-Oppenheimer approximation when electronic states come close in energy. Ultrafast non-radiative decay channels open up in the vicinity of a CI, thus funneling a molecule from one electronic state to another. LÄS MER
