The Fraunhofer Institute for Laser Technology ILT established and hosted the first international conference on laser polishing. From May 6-7, 2014, over 70 local and international scientists and laser technology users from various sectors of the industry met in Aachen, Germany. During five different sessions, 14 speakers from six countries expounded topics related to the laser polishing of glass and metals.
Despite a steady increase in recent years in the number of working groups, publications and projects on the subject, laser polishing is still considered a niche technology.

This prompted Fraunhofer ILT to organize the 1st Conference on Laser Polishing LaP 2014 in Aachen, Germany. Headed by Dr. Edgar Willenborg, their event created an international platform for exchanging scientific findings in the laser polishing field. A total of 14 lectures were held in English, providing over 70 participants from 10 countries with the opportunity to gain a comprehensive picture of latest scientific developments and first industrial applications of laser polishing.
Industrial laser polishing
Dr. Thomas Kiedrowski (Robert Bosch GmbH) introduced a metal polishing application that is already in use today and with which millions of components are laser-polished annually. His presentation centered on an example taken from CVT production.
Two lectures given by Dr. Manyalibo Matthews (Lawrence Livermore National Laboratory) and Dr. Philippe Cormont (CEA CESTA) explained another way in which these new methods are being employed successfully, this being to repair optics for high-power laser systems by means of CO2 laser radiation.

In addition to the lectures, a further highlight for conference participants was a tour of the laboratories at Fraunhofer ILT that let them see the latest laser polishing machines and test set-ups. Among other things, visitors were shown a live demonstration of the adaptive laser polishing machine for the polishing of metal work pieces that was developed as part of the BMBF-funded ALPINE project.
The success of the 1st Conference on Laser Polishing – LaP 2014 reflects the great interest the scientific and industrial communities have in this new manufacturing process. There is clearly a significant demand for a cost-effective, automated finishing process that offers an alternative to conventional abrasive methods. This demand will continue to drive research in this area in the future, so we can expect more exciting developments in the field of laser polishing to be unveiled at the 2nd Conference on Laser Polishing – LaP 2016 from April 26-27, 2016 in Aachen.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
