The study of laser-matter interaction at high intensities has become a field at the forefront of modern physics. Numerous novel effects at high intensities have been discovered, as above threshold ionization and stabilization in high-field atomic physics, as high harmonic generation in non-pertubative non-linear optics or guiding and channeling processes and hot electron formation in relativistic laser-plasma interactions. Furthermore, the use of intense short laser pulses has opened new possibilities for the generation of coherent and incoherent x-rays with important applications in science and technology. In this common project it is planned to study high-intensity laser-matter interaction especially at short wavelengths in order to evaluate possible advantages of short-wavelength laser systems for nonlinear optical processes to generate powerful coherent vuv and xuv radiation and for the efficient conversion of laser radiation into incoherent x-rays. The investigations will also include the development of corresponding shortwavelength laser sources and the up-scaling to ultrahigh intensities. It detail, the IOQ will investigate the conversion of laser radiation at wavelengths of 400 nm and below into incoherent x-rays, the IQ will investigate low order nonlinear optical frequency conversion of short-pulse KrF laser radiation at 248 nm to generate powerful coherent radiation at specific wavelengths (150 nm, 82.8 nm and 49.7 nm) and the LLG will study the short-pulse amplification and energy extraction of discharge and e-beam pumped KrF amplifiers to realize, in cooperation with the CIAE, systems with intensities in the range of 1020 Wcm-2.
