  2. 1. Attosecond Wave Packet Metrology

    Author : Marko Swoboda; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dissociation; Electron wave packets; Pulse characterization; Two-color harmonic generation; Attosecond pulse trains; Single attosecond pulses; Resonant two-photon ionization; Fysicumarkivet A:2010:Swoboda;

    Abstract : Attosecond pulses allow the study of electrons on their natural timescale. They are created from the interaction of atoms with ultrashort, intense laser pulses whose electric field approaches the strength of inner-atomic electric fields. This thesis presents experiments around the generation, characterization and application of attosecond pulses. READ MORE

  4. 2. Scaling and Gating Attosecond Pulse Generation

    Author : Christoph Heyl; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherent imaging; Ultrafast electron dynamics; Single attosecond pulses; Attosecond pulse trains; XUV sources; High-order harmonic generation; XUV frequency combs; Fysicumarkivet A:2014:Heyl;

    Abstract : High-order harmonic generation (HHG) provides the basis for attosecond light sources delivering coherent pulses in the extreme ultraviolet spectral region. Such light sources are employed for a variety of applications within imaging, attosecond spectroscopy, and high-precision frequency metrology. READ MORE

  5. 3. Non-linear attosecond physics at 100 eV

    Author : Alexander Muschet; Laszlo Veisz; Piotr Matyba; Per Eng-Johnsson; Umeå universitet; []

    Abstract : 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. READ MORE

  6. 4. Attosecond Electron Wave Packet Interferences

    Author : Thomas Remetter; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attosecond Bound Electron Wave Packet Dynamics; Attosecond Pulse Train; High-Order Harmonics; Electron Wave Packet Interferometry; Attosecond Physics;

    Abstract : Attosecond pulses offer a new route to produce temporally localized electron wave packets (EWPs) that can easily be tailored by altering the properties of the attosecond pulses. In this thesis we will present different experiments, supported by theory, where attosecond EWPs are created in presence of a strong infrared (IR) field. READ MORE

  7. 5. Generation of Ultrashort Pulses – From Femtoseconds to Attoseconds

    Author : Maite Louisy; Atomfysik; []
    Keywords : Attosecond; Femtosecond; Ultrashort laser pulses; Ultrafast optics; High-order harmonic generation; extreme ultraviolet; Post-compression; Hollow-core capillary; d-scan; Optical gating; Fysicumarkivet A:2017:Louisy;

    Abstract : Electronic dynamics takes place on the attosecond timescale and can thus only be studied using a tool with attosecond temporal resolution. High harmonic generation (HHG) provides coherent attosecond pulses in the extreme ultraviolet spectral region. READ MORE
