The VUV TESLA FEL delivers radiation of peak power in the order of 1 GW in a short pulse of only 50-100 fsec. Such power levels are typical for laser ablation using conventional pulsed lasers. Theoretical predictions and very few experiments indicate that the behaviour of the solid matter under such conditions can differ substantially from that observed when the irradiation pulse durations are in the picosecond or nanosecond region. Investigation of the structure and microstructure of solids exposed to this type of irradiation is crucial to understand damage mechanisms in materials, and can imply also promising applications in various areas of nanotechnology.
