Does laser radiation react differently with the target material under high pressure? How do the extreme conditions of the deep sea affect machining processes? The Laser Zentrum Hannover e.V. (LZH) can investigate these and other questions with a specially developed pressure chamber and simulate deep-sea conditions.
With the pressure chamber of the LZH, a water depth of 6,500 meters can be simulated with a pressure of up to 650 bar.
With the special pressure chamber at the LZH, laser material processing can be tested under deep-sea conditions.
The chamber is suitable for both freshwater and saltwater and can thus represent various application scenarios. The pressure chamber includes a special device in which the sample can be placed safely.
Watching the live process
In the pressure chamber two different viewing windows (25 mm and 80 mm) can be used. These allow to introduce laser radiation and to observe the process with a camera. Thus, the scientists can, for example, analyze the plasma formation on the surface of the sample.
This is interesting for the preparation of deep-sea work and measurements, as in the current ROBUST project at the LZH that focuses on the investigation of mineral resources on the seabed.
Pressurization of materials
Furthermore, the chamber can be used to examine different materials for their reaction to high pressures under water. Using high-speed camera technology, the LZH can record full HD video material at over 12,000 images per second and synchronize it with the pressure curve in the chamber.

Since their experimental discovery, magnetic skyrmions - tiny magnetic knots - have moved into the focus of research. Scientists from Hamburg and Kiel have now been able to show that individual magnetic skyrmions with a diameter of only a few nanometres can be stabilised in magnetic metal films even without an external magnetic field. They report on their discovery in the journal Nature Communications.
The existence of magnetic skyrmions as particle-like objects was predicted 30 years ago by theoretical physicists, but could only be proven experimentally in...
Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine - which, as a single calcium ion, is approximately ten billion times smaller than a car engine.
Work performed by Professor John Goold's QuSys group in Trinity's School of Physics describes the science behind this tiny motor.
Together with the University of Innsbruck, the ETH Zurich and Interactive Fully Electrical Vehicles SRL, Infineon Austria is researching specific questions on the commercial use of quantum computers. With new innovations in design and manufacturing, the partners from universities and industry want to develop affordable components for quantum computers.

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
