Nonlinear optics and high intensity laser-plasma interaction


Research objectives and content
Nonlinear optical phenomena are playing an increasingly important role in modern physics and technological applications. The recent revolution in the development of high power laser sources gives access to new physical parameter regimes where entirely new optical phenomena are expected and possible applications involve a broad range of scientific and technological applications. However, it should be emphasized that the importance of nonlinear optical effects increases, also at moderate light intensities. An example of this is provided by optical fibre communication systems, where the drive towards higher transmission rates involves using optical fibres with small chromatic dispersion. This development correspondingly enhances the relative importance of the inherent Kerr nonlinearity of the optical fibre, which tends to become the limiting physical factor for the transmission capability of the system, In spite of the large difference in the absolute values of the intensities involved in the two applications mentioned, many of the optical phenomena which occur are very similar. The aim of the present project is to provide a good research training in nonlinear optics with special emphasis put on the synergistic effects that can be reached by working in an interdisciplinary manner in the intersection of the above mentined physics areas.
Training content (objective, benefit and expected impact)
The objective of the project is to provide the applicant with a good research training in nonlinear electromagnetics in general and optics in particular. Special emphasis will be given to applications of nonlinear effects in laser-plasma interactions and optical fibre communication systems. The project is planned to lead to a PhD exam for the applicant. Links with industry / industrial relevance (22)
The research group at Chalmers is well established within the scientific community in nonlinear optics and has also strong links with Swedish telecommunication industry with which collaboration is currently going on e.g. on the effects of fibre nonlinearity in different schemes for dispersion compensation in high speed optical communication systems.
