  1. 1. Time-Frequency Analysis in Attosecond Spectroscopy

    Detta är en avhandling från Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Författare :Marcus Isinger; Lunds universitet.; Lund University.; [2018-12]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attosecond; Spectroscopy; Time-Frequency; High-order harmonic generation; Rabitt; Interferometry;

    Sammanfattning : This thesis deals with ultrafast dynamics of electronic processes in rare gas atoms. The processes we explore include photoemission, where we time the emission of electrons moving away from the atomic core following ionization by a photon; and auto-ionization, where the atom spontaneously releases an electron wave-packet following photo-excitation.

  2. 2. Probing Electron Correlation on the Attosecond Timescale

    Detta är en avhandling från Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Författare :Diego Guenot; Lunds universitet.; Lund University.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Guénot;

    Sammanfattning : Popular Abstract in English Imagine you are sunbathing on a sandy beach, while reading the latest Dan Brown book. Once the book is finished, you look at the waves and notice that in one place, they decelerate and become large. LÄS MER

  3. 3. Measurement and Control of Attosecond Light Fields

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Erik Mansten; Lunds universitet.; Lund University.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pulse characterization; Spectral signature; Two-color generation; Pulse compression; Attosecond pulse trains; High-order harmonics; Pulse shaping; Tunable; Fysicumarkivet A:2009:Mansten;

    Sammanfattning : Attosecond pulses are used to study electron dynamics in atoms and molecules. In this thesis, schemes to control the generation of attosecond pulses and pulse-shaping techniques to compress the pulses are presented. Generation of attosecond pulses requires high intensity, which is reached by focusing a pulsed femtosecond laser. LÄS MER

  4. 4. Light-Matter Interaction on the Attosecond Timescale

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Marcus Dahlström; Lunds universitet.; Lund University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2011:Dahlström; Temporal characterization; Two-color harmonic generation; High-order harmonic generation; Attosecond pulse trains; Electron wave packets; Two-photon ionization; Coherent control;

    Sammanfattning : Popular Abstract in Swedish När ljus belyser ett material kan elektroner frigöras via en process som kallas den fotoelektriska effekten. Experiment utförda under slutet av 1800-talet visade att det inte är styrkan på ljuset som avgör om elektroner kan frigöras, det är istället ljusets färg. LÄS MER
