Forscher um Dr. Nina Rohringer vom Hamburger Center for Free-Electron Laser Science (CFEL) haben am kalifornischen Forschungszentrum SLAC den ersten Röntgenlaser auf Atom-Basis konstruiert. Mit Hilfe von Neonatomen erzeugten sie ultrakurze Röntgenblitze von einzigartiger Farbreinheit. Das erlaubt in vielen Fällen einen schärferen Blick in die Nanowelt, wie die Wissenschaftler im britischen Fachjournal "Nature" berichten (DOI: 10.1038/nature.10721). Das CFEL ist eine Kooperation des Deutschen Elektronen-Synchrotrons DESY, der Max-Planck-Gesellschaft und der Universität Hamburg.
Max-Planck-Forscherin Rohringer und ihre Kollegen vom Lawrence Livermore National Laboratory und der Colorado State University nutzten für ihre Versuche den sogenannten Freie-Elektronen-Laser LCLS am SLAC.
