The development of ultra-short-pulse disk lasers (UKP lasers) with a high midrange power is being substantially supported by the EU for three years. The scientific and strategic commitment by the Institute for Laser Tools (IFSW) at the University of Stuttgart to develop the next generation of ultra-short-pulse disk lasers is now leading into two STReP projects (Specific Targeted Research Projects) in the framework of the 7th European Subsidy Programme of the EU. The project is planned to start on 1st November 2013.
University of Stuttgart (IFSW)
Both projects have the aim of disk lasers with several hundred watt midrange power, the one with particularly short pulses (shorter than a tenth of a billionth of a second) on the basis of mutually cooled laser disks made of titanium sapphire (sapphire fortified with titanium), the other with a crystalline wave guide as a pre-amplifier and a laser disk as a main amplifier for cylindrically polarised pulses with a duration of some billionths of seconds. Together the projects have a volume of 9.14 million €, whereby the financial support provided by the EU amounts to 6.37 million €, of which the IFSW will receive 1.9 million €. The projects are coordinated at the IFSW in the business division for laser development and laser optics headed by Dr. Abdou Ahmed.
Prof. Thomas Graf, Head of the Institute for Laser Tools at the University of Stuttgart, commented on the success story: “Along with the very interesting scientific challenges, the development of new ultra- short-pulse disk lasers with a high midrange power is also of great scientific interest with a view to the increase in productivity with the laser-based material processing”.
The consortia comprise the renowned partners: Thales Optronique SA (France), Element Six Ltd. (UK), Centre National de la Recherche Scientifique - CNRS (France), Oxford Lasers Ltd. (UK) and M-Squared Lasers Ltd. (UK) for the development of the titanium sapphire disk lasers (coordination Dr. A. Voß, IFSW, University of Stuttgart, Germany) as well as Time-Bandwidth Products AG (Switzerland), Centre National de la Recherche Scientifique - CNRS (France), Fibercryst SAS (France), Next Scan Technology B.V. (The Netherlands), GFH GmbH (Germany), Schweißtechnische Lehr- und Versuchsanstalt SLV Mecklenburg-Vorpommern (Germany) and Class 4 Laser Professionals AG (Switzerland) for the project on the ultra-short-pulse laser disks with cylindrical polarisation (coordination Dr. M. Abdou Ahmed, IFSW, University of Stuttgart, Germany).Further information:

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
