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

    Author : Samuel Bengtsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; extreme ultraviolet; controlled emission; Free induction; time-dependent spectroscopy; noble; High order harmonic generation; phase-control; Fysicumarkivet A:2017:Bengtsson;

    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

  2. 2. Laser-Plasma Sources for Extreme-Ultraviolet Lithography

    Author : Björn Hansson; KTH; []
    Keywords : fluid and plasma; radiation; electronics; electrical;

    Abstract : This thesis describes the development and characterizationof a liquidxenon- jet laser-plasma source forextreme-ultraviolet (EUV) radiation. It is shown how thissource may be suitable for production-scale EUV lithography(EUVL). READ MORE

  3. 3. Characterisation and Applications of Ultrashort Extreme Ultraviolet Pulses

    Author : Johan Norin; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ultrashort pulses; pulse characterisation; sidebands; interferometry; Atom- och molekylärfysik; acetylene; Atomic and molecular physics; High-order harmonics; XUV; Fysicumarkivet A:2002:Norin;

    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

  4. 4. Towards ultrafast imaging with extreme ultraviolet light sources

    Author : Jörg Schwenke; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photo emission electron microscopy; Focusing of X-ray radiation; Digital holography; High-order harmonic generation; Free-electron laser seeding; Secondary electron cascades; Fysicumarkivet A:2012:Schwenke;

    Abstract : This thesis reports experimental studies performed with two advanced coherent XUV sources with ultrashort pulse duration, high-order harmonic generation and seeded-free electron laser. High-order harmonic generation (HHG) is the generation of overtones of a fundamental laser pulse in a medium, e.g. noble gases. READ MORE

  5. 5. Control of Coherent Extreme Ultraviolet Light and Light Sources

    Author : Neven Ibrakovic; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ultrafast lasers; XUV optics; high-order harmonic generation; quantum path interference; opto-optical modulation; free electron lasers; nitrogen lasing; Fysicumarkivet A:2019:Ibrakovic;

    Abstract : Coherent extreme ultraviolet (XUV) light sources are necessary for the investigation of physical processes in the natural length and time scales of atoms. These experiments require a high degree of control of the coherent XUV light. READ MORE
