The characterization of a single laser pulse in real-time is of great interest. Here, the difficulty of detection originates from the required resolution in time (about a factor of ten higher than the measuring pulse). This concerns not only the sampling resolution but the sampling rate as well.<br><br> The invention allows single-shot laser pulse characterization with a time resolution in the THz regime. It consists of a laser system that provides the sampling pulse, an optical element (e.g. non-linear crystal) which generates the measuring signal through superposition of the sampling pulse and the measuring pulse, and a third element for the detection.<br><br> The method based on the transformation of the problem from the time domain into the spectral domain. The sampling laser is a laser system which provides light pulses that have different wavelengths at different time. With an optical element (e.g. grating) it is possible to seperate the wavelength components in space. Therefore, the detection of the sampling points with minimal spatial distance is possible without any problem. This means, every spectral component can be assigned to a distinct time. <br><br> This single-shot optical sampling offers a resolution in the femtosecond time domain.<br><br>

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...
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...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

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.
