1. Second-generation High-Order Harmonic Sources — From CPA to OPCPA
Abstract : This thesis presents two sources of extreme ultraviolet (XUV) radiation based on high-order harmonic generation (HHG) in gases. The sources were developed for experiments requiring high-flux harmonic beams or HHG pulses at high-repetition rate. These were used experimentally to image nano-scale objects. READ MORE

2. A sub-5 fs 100 TW optical parametric synthesizer
Abstract : State-of-the-art ultrashort light sources in the visible and near-infrared spectral regions provide direct access to the femtosecond realm, thereby enabling understanding and control of electronic processes within matter. On the other hand, ultra-intense light pulses lead to the emergence of relativistic electron motion and many related phenomena, such as electron & ion acceleration and high-order harmonic generation in plasmas.

3. Generation, characterization and application of infrared few-cycle light pulses
Abstract : In recent decades, laser systems emitting pulses of light containing only a few electric field oscillations under their envelope have become common in many ultrafast optics laboratories. Owing to unique temporal characteristics and achieving extreme field strengths, these so-called few-cycle pulses have been instrumental in unlocking new regimes of light-matter interaction. READ MORE

4. Photoemission Electron Microscopy for Ultrafast Nano-Optics - Femtoseconds to Attoseconds
Abstract : Ultrafast nano-optics is a new and quickly evolving research field centred around the control, manipulation, and application of light on a nanometre and femtosecond scale. This can lead to improved electro-optical devices, more sensitive spectroscopy, and real-time control of chemical reactions. READ MORE

5. Ultrafast Photoionization Dynamics Studied with Coincidence Momentum Imaging Spectrometers
Abstract : The time scale of the dynamics in atoms and molecules varies from attoseconds (10-18) to picoseconds (10-12) depending on the size of the particles. To study such dynamics, ultrafast light pulses are needed to trigger and capture the reaction. One of the most direct methods consists in ionizing the system and observing the following response.
