Accelerator-based high-energy electron diffraction determines 3D atomic structure of materials New method using ultrashort ...

When laser energy is deposited in a target, numerous complex processes take place too rapidly to observe visually. To study and adapt such processes, researchers often use computer modeling. However, ...

Those who have experienced method development for laser diffraction understand the scenario well: you are dealing with a new type of sample, uncertain about handling a particular detail, and the one ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

At high power, laser light inside a multimode optical fiber is supposed to misbehave. The beam usually breaks into a noisy, ...

Can light behave like a whirlwind? It turns out it can—and such "optical tornadoes" have now been created in an extremely small structure by scientists from the Faculty of Physics at the University of ...

Infrared light passes through the metal lens and is converted into violet light and focussed in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.
