High-Intensity lasers in nuclear physics: status report on laser-based free-electron lasers — •Florian Grüner¹, Stefan Becker¹, Matthias Fuchs¹, Raphael Weingartner¹, Ulrich Schramm², and Dietrich Habs¹ — ¹University of Munich, Depart. of Physics, Am Coulombwall 1, 85748 Garching — ²Forschungszentrum Dresden-Rossendorf, FZD, 01314 Dresden

World-wide there is a boom in laser-plasma accelerators, where high-intensity lasers produce brilliant electron and ion beams. Together with this development there is an international race on realizing a laser-based free-electron laser (FEL). We give a report on the status of our experiments as well as on further design studies. One aim of the studies is to extend the photon energy from FELs towards the medically relevant energy region above 20 keV and even further towards a γ−-FEL delivering an ultra-brilliant beam of MeV-photons. Such a beam could be used for generating low-energy neutrons by the nuclear photo effect. A 20-keV-FEL could be used to produce coherent Moessbauer excitations and drive a γ−-laser.
