This group provides a focus for activities related to the development and application of high intensity lasers as well as novel XUV and x-ray sources. Specific interests include the technology of high intensity, ultrafast lasers, the physics of high intensity light interactions with matter, and the generation of high brightness short wavelength radiation with ultrafast lasers. Part of the group is also interested in advances in traditional short wavelength sources including insertion devices for storage rings (undulators and wigglers), plasma X-ray lasers, electron beam based sources and X-ray free electron lasers. At the leading front of the attosecond science the group will also embrace attosecond pulse generation and its surface- and volume-interaction with solid state, liquid and gaseous materials, including biological and organic materials and nanomaterial structures. The group intends to serve fundamental researchers as well as the technological and industrial community.
