  1. 1. Ultrafast opto-optical control of extreme ultraviolet light pulses

    University dissertation from Atomic Physics, Department of Physics, Lund University

    Author : Samuel Bengtsson; Lunds universitet.; Lund University.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extreme ultraviolet; controlled emission; Free induction; time-dependent spectroscopy; noble; High order harmonic generation; phase-control;

    Abstract : Extreme ultraviolet (XUV) light is a valuable frequency range for ultrafast optics experiments. The short wavelength is a requirement for ultrashort pulses, which are widely used to characterize fast dynamics. Additionally, the high photon energy enables quantum control of high frequency transitions in atoms. READ MORE

    Abstract : When a strong laser field interacts with free atoms, harmonics up to very high orders are created. This extreme ultraviolet (XUV) radiation has interesting properties, such as spatial and temporal coherence, short pulse duration and high brightness. This thesis concentrates on the temporal aspects of this radiation. READ MORE

    Abstract : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.
