Fibre laser quietly revolutionizes the world

08.10.2009
For more than 50 years lasers have been successfully established in research and industry. Now, a special configuration is taking the fast lane: the fibre laser.

Its advantages are obvious: due to the fibre design the beam quality is close to perfect, hence best possible focus ability even with very long operating distances is ensured.

Flexible fibre geometry and vibration insensitivity as well as high efficiency and low operating costs convincingly allow an uncomplicated integration in industrial, automated production processes. Compared to conventional materials processing, the laser machining entails positive features, namely minor limitations regarding processable materials, non-contact treatment and high beam scanning speed as well as maximum accuracy.

A diversified consortium on the European level will work together to set new standards in the field of fibre laser technology. Main objective of the nearly 16 m. EUR EU-project LIFT - Leadership in Fibre laser Technologies, - starting in September 2009, is the offensive consolidation of Europe's scientific, engineering and production-related leadership position. Coming from 9 different countries, expertises of 15 decisive companies, among them two Fraunhofer institutes, three universities and one non-profit-organization joined and constitute a strong consortium.

Managed by the Fraunhofer-Institute for Material and Beam Technology IWS Dresden, laser suppliers, producers of optical and opto-electronic components, manufacturers of photonic fibres and fundamental researchers as well as application engineers will work on several goals.

The consortium will focus on the development of fibre-based short pulse lasers for so called gentle "cold treatment" of materials, in particular for special ceramic-materials, being of increasing interest in various areas. Another key role plays the progression of ultra reliable, pulsed high-performance-fibre laser systems which will significantly enhance processes like remote-laser cutting or welding in their efficiency.

A specific challenge within the medical sector will be the realization of a three-colour fibre laser. The aim is to develop a narrowband fibre laser system which is continuously emitting VIS radiation at wavelengths specifically chosen to treat various symptoms like acne or retina indisposing. Furthermore, this laser system will permit to combat certain types of cancer via photodynamic therapy.

Additionally, the project addresses the sector of renewable energies. As the technical efficiency of photoelectric cells reaches its upper limit, the consortium will focus on the improvement of individual production steps in the manufacturing of solar modules. Pulsed high performance fibre-laser systems in combination with intelligent remote-beam delivery components will allow the up to now very intricate large area processing of solar substrates.

Almost unnoticed by the end user, the fibre laser proceeds on its way to a crucial component of Europe's high technology and so quietly revolutionizes the production and medical technology of tomorrow.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
