Division A: Attosecond Physics
Director: Prof. Dr. M. Vrakking, Free University of Berlin

The research profile of division A is based on long standing experience in chemical physics. It also makes use of a broad expertise in ultra short experimental and theoretical physics.

Division A is - jointly with division C - responsible for the development and operation of the femtosecond application laboratories of the MBI. In addition, division A manages the laboratory facility for combined experiments with laser and synchrotron radiation at BESSY II.

See also Topical seminars of Division A.

Division A is substructured in three departments:  
Department Department head
  A1 Attosecond Theory Prof. Dr. M. Ivanov
  A2 Ultrafast XUV-Physics Dr. O. Kornilov
  A3 Ultrafast Lasers and Nonlinear Optics N. N.
The titles of the departments indicate the know-how available in Division A.
In summary the areas of competence are described as follows:
  • surface physics and measuring techniques; femtosecond laser application to surfaces, combined experiments with laser and synchrotron radiation

  • laser spectroscopy and real time studies of free clusters, bio-molecules and He-nanodroplets involving complex experimental setups with time resolved multi colour pump-probe measurements
  • molecular beam techniques, cluster sources, fotoion-fotoelectron-coincidence, spatially resolved particle detection
  • free cluster studies with synchrotron radiation; photoemission from liquid water jets and salt solutions
  • development of fs-laser systems (sub-50 fs - 2 ps) with special properties for selected applications; measurement and manipulation of laser parameters by non linear optical methods, in particular in extreme spectral ranges such as in the VUV
  • micro material structuring with fs - lasers
  • synthesis of organic molecules (extended pi-systems) for special thin film functions
  • generation and propagation of ultrashort light pulses
  • ab-initio-calculations for small cluster structures and model calculations for the ultra fast dynamics of clusters

In the framework of the research structure of the MBI, scientists of division A participate in the following projects:
