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>

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
