  1. 1. Dynamic Stark Shaping of Molecular Fate

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sharon Berkowicz; [2019]
    Keywords : Dynamic Stark effect; Dynamic Stark Control; Oxygen; Photodissociation; Photochemistry; Laser Spectroscopy; Dynamiska Starkeffekten; Dynamisk Starkkontroll; Syre; Fotodissociation; Fotokemi; Laserspektroskopi;

    Abstract : The dynamic (ac) Stark effect refers to the energy shifting of electronic states induced by an oscillating electric field. Conveniently, the magnitude of the ac Stark shift scales with the square of the electric field amplitude, i.e. with light intensity. READ MORE

  3. 2. 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. 3. Compression and Shaping of Femtosecond Laser Pulses for Coherent Two-Dimensional Nanoscopy

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

    Author : Lukas Wittenbecher; [2016]
    Keywords : Femtosecond pulse shaping; Ultrafast optics; Liquid crystal spatial light modulator; Coherent two-dimensional nanoscopy; Dispersion compensation; Physics and Astronomy;

    Abstract : Femtosecond pulse shaping is a versatile tool that enables the generation of ultrashort laser pulses with nearly arbitrary temporal shapes. Among others, the technique is of use in ultrafast spectroscopy experiments where it can be employed for dispersion control and the generation of well-defined laser pulse sequences. READ MORE
