  3. 22. 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. 23. 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.

  5. 24. Towards the carrier-envelope phase stabilization of a16 TW 4.5 fs laser system

    University essay from Umeå universitet/Institutionen för fysik

    Author : Emil Thorin; [2018]
    Keywords : ;

    Abstract : In the last decades the scientific development has made it possible to produce pulses with durations below the femtosecond time scale (1 fs = 1015 s), reaching to attoseconds (1 as = 1018 s). This is the time scale of electronic motion inside atoms and molecules. READ MORE

  6. 25. Photoelectron Spectroscopy using high repetition rate attosecond pulses

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

    Author : Lisa Rämisch; [2017]
    Keywords : Physics and Astronomy;

    Abstract : In attosecond physics, pump-probe experiments have been a promising tool to study the fundamental light-matter interaction process of photoionization. In this context, photoelectron spectroscopy is used to spatially and temporally characterize the ejected photoelecron. READ MORE
