    Sammanfattning : 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.

    Sammanfattning : Recent advances in laser technology, with the development of extremely short-pulse, high-intensity lasers, have opened doors to new areas in atomic physics. By focusing light from an intense, short-pulse laser into a gas jet, the emission of high-order harmonics of the laser frequency has been studied. LÄS MER

  7. 5. Experimental Techniques for Studies in Atomic & Molecular Physics

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spectroscopy; fast ion beam laser spectroscopy; time of flight photoelectron photoelectron coincidence; hyperfine structure; Rabi oscillation; Physics; Fysik;

    Sammanfattning : This thesis is based on a selection of six different experimental techniques used for studies in atomic and molecular physics. The techniques analysed in the thesis are compared to find similarities in strategies and ways to avoid sources of error.Paper 1 deals with collision based spectroscopy with 60 keV Xe6+ ions on sodium and argon gas targets.
