Mit einem offiziellen ersten Spatenstich begeht die Physikalisch-Technische Bundesanstalt (PTB) am 12. Juli den symbolischen Bauauftakt für ein hochspezialisiertes Forschungsgebäude. Der neue Walther-Meißner-Bau bietet Labor-, Mess- und Reinräume für höchst genaue Messungen der Temperatur und für Forschungsarbeiten rund um supraleitende Sensorik. Für diese High-Tech-Aufgaben wird das Gebäude mit besonders hochwertiger Bau- und Gebäudetechnik versehen. Der Entwurf für den Neubau stammt von Rohdecan Architekten aus Dresden, die 2014 aus einem vom Bundesamt für Bauwesen und Raumordnung (BBR) ausgelobten Wettbewerb siegreich hervorgingen.

No one had ever come so close to the ideal laser before: theoretically, laser light has only one single color (also frequency or wavelength). In reality, however, there is always a certain linewidth. With a linewidth of only 10 mHz, the laser that researchers from the Physikalisch-Technische Bundesanstalt (PTB) have now developed together with US researchers from JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado, Boulder, has established a new world record. This precision is useful for various applications such as optical atomic clocks, precision spectroscopy, radioastronomy and for testing the theory of relativity. The results have been published in the current issue of "Physical Review Letters".

An overview of the diverse research landscape of PTB as well as some particularly highlighted topics (for example, PTB research surrounding the International System of Units SI) you will find in the chapter Opens internal link in current windowResearch & Development). In addition, it is always worthwhile to look at the Opens internal link in current windowmain Homepage as well as the homepages of the respective Opens internal link in current windowDivisions. How reputable PTB is among researchers you can see at Opens internal link in current windowPTB in the World of Research. Furthermore, PTB has been – specifically its R&D component, in particular – evaluated repeatedly with excellent results. You can download the respective documents (which are in German only) in the right column as a pdf file.

Scientific publications
