Substantial EU financial support

Success in disk laser research with a rich tradition at the University of Stuttgart

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).

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
