Shaking the topological cocktail of success

Graphene is the miracle material of the future. Consisting of a single layer of carbon atoms arranged in a honeycomb lattice, the material is extremely stable, flexible, highly conductive and of particular interest for electronic ...

Researchers make optical fibers from common materials

Clemson researchers are taking common materials to uncommon places by transforming easily obtainable and affordable materials into fiber. Their findings are published in Nature Photonics, the world's top journal focused on ...

A laser for penetrating waves

The Landau-level laser is an exciting concept for an unusual radiation source. It could efficiently generate so-called terahertz waves, which can be used to penetrate materials, with possible applications in data transmission. ...

Topological charges of periodically kicked molecules

The peculiar topological properties of some forms of matter have been researched for decades. Now, researchers at the Institute of Science and Technology Austria (ISTA) have discovered topological properties of simple diatomic ...

A laser focus on super water-repellent metals

In a laboratory at the University of Rochester, researchers are using lasers to change the surface of metals in incredible ways, such as making them super water-repellent without the use of special coatings, paints, or solvents.

A milestone in ultrashort-pulse laser oscillators

With the demonstration of a sub-picosecond thin-disk laser oscillator delivering a record-high 350-watt average output power, physicists at ETH Zurich set a new benchmark and pave the path toward even more powerful lasers.

How to take a picture of a light pulse

Until now, complex experimental equipment was required to measure the shape of a light pulse. A team from TU Wien (Vienna), MPI Garching and LMU Munich has now made this much easier.
