  4. 3. Atomic and Molecular Dynamics Probed by Intense Extreme Ultraviolet Attosecond Pulses

    Författare :Jasper Peschel; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attosecond science; Ultrafast phenomena; High-order Harmonics Generation; Free Electron Lasers; Photoionization; Photodissociation; Fysicumarkivet A:2021:Peschel;

    Sammanfattning : This thesis work was aimed to investigate dynamical processes in atoms and molecules on ultrafast time scales initiated by absorption of light in the extreme ultraviolet (XUV) regime. In particular, photoionization and photodissociation have been studied using pump-probe techniques involving ultrafast laser pulses. LÄS MER
