  1. 1. Noncollinear optical parametric amplification of a supercontinuum

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Åkesson; [2019]
    Keywords : optical parametric amplification; supercontinuum generation; nonlinear optics; laser pulse compression; lasers; optics; Physics and Astronomy; Technology and Engineering;

    Abstract : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). READ MORE

  2. 2. Design and Commissioning of an Ionization Intensity Monitor

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Hanna Berg; [2019]
    Keywords : Physics and Astronomy;

    Abstract : The dynamics of molecules and electrons takes place on timescales of femtoseconds and attoseconds, respectively. This requires ultrashort and intense extreme ultraviolet (XUV) pulses to be able to study them. READ MORE

  3. 3. Dependency of high-order harmonics to polarisation properties of many-cycle driving fields

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Timothé Ramboazanaka; [2018]
    Keywords : Atomic physics; attosecond pulses; high-order harmonic generation; polarisation; polarisation state; electron wave packet trajectory; three-step model; time-dependent schrödinger equation; TDSE; two-colour; selection rules; symmetry; conservation laws; Physics and Astronomy;

    Abstract : Light-matter interactions can be used to probe both light and matter as they yield information on a system's state. On the ultrafast timescale, it is possible to employ these interactions to probe fast-occurring phenomena. READ MORE

  4. 4. Possibilities and Challenges in Temporal Control of XUV Pulses by Opto-optical Modulation

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Anna Olofsson; [2018]
    Keywords : Quantum Control; Atomic physics; ultrashort pulses; attosecond science; ultrafast optics; nonlinear optics; opto-optic modulator; Physics and Astronomy;

    Abstract : Recent developments in opto-optical modulation technique calls for improved temporal control of light modulation processes of coherent XUV light. This thesis project evaluates an experimental method aimed at achieving redirection and amplitude modulation of XUV-light, by using precise determination of decay times in states of noble gases that are deemed suitable for opto-optical control.
