2. 1. Temporal Aspects of High-Intensity Laser-Matter Interactions

   Author : Johan Mauritsson; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Laser technology; Relativistic Self-Focusing; High-Intensity Lasers; Attosecond Pulses; Pulse Characterization; XUV; High-Order Harmonics; Ultrashort Pulses; Laserteknik; Atom- och molekylärfysik; Atomic and molecular physics; Fysicumarkivet A:2003:Mauritsson;

   Abstract : The availability of short-pulse, high-intensity lasers has opened doors to new areas in atomic and plasma physics. The short pulses (a few femtoseconds), that are available today, enable unprecedented temporal measurements, while the high peak power accessible (several terawatts) allows physicists to study the interaction between light and relativistic plasmas.

4. 2. Radiation in simulations of high intensity laser-matter interaction

   Author : Erik Karl Wallstén Wallin; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; plasma; nonlinear dynamics; particle-in-cell; Manley-Rowe; radiation reaction; synchrotron radiation;

   Abstract : We consider electromagnetic waves propagating in plasmas, with two main themes covered. First nonlinear plasma theory and wave-wave interaction. Here a wave-wave symmetry, the Manley-Rowe relations, is used as a method of determining the physicality of modified plasma fluid equations. READ MORE

5. 3. Relativistic light-matter interaction

   Author : Tor Kjellsson Lindblom; Eva Lindroth; Bernard Piraux; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time-dependent Dirac equation; Beyond dipole effects; Relativistic effects; High-Intensity laser-matter interaction; teoretisk fysik; Theoretical Physics;

   Abstract : During the past decades, the development of laser technology has produced pulses with increasingly higher peak intensities. These can now be made such that their strength rivals, and even exceeds, the atomic potential at the typical distance of an electron from the nucleus. READ MORE

6. 4. Modelling of laser plasma interaction with applications

   Author : Benjamin Svedung Wettervik; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electron wakefield acceleration; ion acceleration; coherent X-ray pulses; plasma; Vlasov-Maxwell equations; continuum methods; radiation generation;

   Abstract : The development of laser systems with ultra-high intensities has both opened up prospects for compact particle accelerators, as well as probing QED-effects, which are present in the high intensity regime. To describe laser matter interaction, it is necessary to self-consistently account for the paths of a large number of particles and the corresponding electromagnetic fields, with the addition of stochastic effects at high laser intensities.

7. 5. Modelling of laser plasma interaction with applications to particle acceleration and radiation generation

   Author : Benjamin Svedung Wettervik; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasma; ion acceleration; continuum methods; electron wakefield acceleration; raditation generation; coherent X-ray pulses; Vlasov-Maxwell equations;

   Abstract : The development of laser systems with ultra-high intensities has allowed the study of the relativistic interaction of laser light and ionized matter, plasmas, as well as opened up prospects for compact particle accelerators, generation of high intensity X-ray, XUV radiation, and probing QED-effects, which are present in the high intensity regime. To describe laser matter interaction, it is necessary to self-consistently account for the paths of a large number of particles and the corresponding electromagnetic fields, with the addition of stochastic effects at high laser intensities.
