1. Laser-driven beams of fast ions, relativistic electrons and coherent x-ray photons
Abstract : This thesis presents experimental results on the development and optimization of novel and highly compact sources of beams of fast ions, relativistic electrons and coherent x-rays, driven by intense laser-plasma interactions. The rapid development of high-power, short-pulse laser systems have made available peak powers reaching the petawatt regime and focused intensities reaching 10^21 W/cm2. READ MORE

2. Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design
Abstract : Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the ~10 MeV regime. READ MORE

3. Ultra-intense laser-plasma interaction for applied and fundamental physics
Abstract : Rapid progress in ultra-intense laser technology has resulted in intensity levels surpassing 1022 W/cm2, reaching the highest possible density of electromagnetic energy amongst all controlled sources available in the laboratory. During recent decades, fast growth in available intensity has stimulated numerous studies based on the use of high intensity lasers as a unique tool for the initiation of nonlinear behavior in various basic systems: first molecules and atoms, then plasma resulting from the ionization of gases and solids, and, finally, pure vacuum.

5. Towards Single Molecule Imaging - Understanding Structural Transitions Using Ultrafast X-ray Sources and Computer Simulations
Abstract : X-ray lasers bring us into a new world in photon science by delivering extraordinarily intense beams of x-rays in very short bursts that can be more than ten billion times brighter than pulses from other x-ray sources. These lasers find applications in sciences ranging from astrophysics to structural biology, and could allow us to obtain images of single macromolecules when these are injected into the x-ray beam.
