The development and the application of
highly specialized laser systems for experiments at the MBI and for use in combination
with electron accelerators are the major goals of this project. These accelerators include
storage rings and linear accelerators for FELs.
At present, our work is subdivided into the following subtopics:
UP1: Development, installation and maintenance of lasers for
The lasers developed in this project are used at the linear accelerators at the
laboratories of our cooperation partners DESY (operating the FLASH FEL at DESY Hamburg),
the international PITZ Collaboration at DESY Zeuthen, HZB (formerly BESSY) at
Berlin-Adlershof, and FZD Rossendorf, operating the ELBE facility.

UP2: High power femtosecond laser system with shaped pulses
Development of short-pulse laser systems for experiments at the MBI: new ideas and
technological know-how for Ti:Sapphire femtosecond laser systems operated at high average
output power with excellent spatial parameters and programmable temporal wavefronts.
The task is turned to frequency-disperse the pulse in space and
modulate the spectrum and spectral phase by creating a spatially varying transmission
UP3: High-order harmonic beamline
A high-order harmonic beamline has been built to generate frequency-tuneable femtosecond
XUV pulses for time-resolved studies of solids, surfaces and gas phase samples.
The beamline has been developed in the framework of Pakt für Forschung und Innovation,
WGL, in collaboration with Ph. Wernet, K. Godehusen, and O. Schwarzkopf (Helmholtz-Zentrum
Berlin für Materialien und Energie GmbH), and will be offered as a facility open for
