Ultra-thin lenses that make infrared light visible

Researchers have achieved this using a special metal-oxide lens material called lithium niobate and through nanoscale pattern, stamped into the material

03-Jun-2025 - Physicists at ETH Zurich have developed a lens with magic properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used optical devices. Camera lens or objectives, for example, produce a sharp photo or video ...

Milestone for laser technology: Huge research machine much smaller and cost-effective

Research team demonstrates free-electron laser driven by plasma accelerated electron beams and seeded by additional light pulses

07-Dec-2022 - Extremely intense light pulses generated by free-electron lasers (FELs) are versatile tools in research. Particularly in the X-ray range, they can be deployed to analyze the details of atomic structures of a wide variety of materials. Until now, FELs such as the European XFEL in Germany are based ...

High harmonics illuminate the movement of atoms and electrons

Detailed new insights into atomic motions

07-Jul-2022 - Laser light can radically change the properties of solid materials, making them superconducting or magnetic within millionths of a billionth of a second. The intense light causes fundamental, immediate changes in a solid by ‘shaking’ its atomic lattice structure and moving electrons about. But ...

Light-Controlled Reactions at the Nanoscale

Physicists used for the first time laser light to control the location of light-induced reactions on the surface of nanoparticles

23-May-2022 - Controlling strong electromagnetic fields on nanoparticles is the key to triggering targeted molecular reactions on their surfaces. Such control over strong fields is achieved via laser light. Although laser-induced formation and breaking of molecular bonds on nanoparticle surfaces have been ...

Intense laser light modifies the pairing of electrons

Finding lights a way for bottom-up controlling chemical reactions with lasers in the future – based purely on electrons, the “glue” of chemistry

14-Apr-2022 - The quantum-mechanical exchange interaction between electrons, a consequence of the Pauli exclusion principle, can be specifically modified with intense infrared light fields on time scales of a few femtoseconds, as time-resolved experiments on sulfur hexafluoride molecules show. This finding ...

Donuts and laser beams

In materials research, considerable progress is made by exploiting insights from the field of topology: Similar tools can now be applied to lasers

01-Mar-2022 - A donut is not a bun. From a mathematical point of view, they are two fundamentally different objects: The donut has a hole, the bun does not. A circle inside the donut around its hole in the center cannot be shrunk to a point. An arbitrary circle inside the bun, however, can. The mathematical ...

New light source: A million times brighter than the sun

PhD thesis investigated application of a special white-light laser for semiconductor industry and microbiology

14-Feb-2022 - A new high-performance white-light laser is expected to speed up quality control in the semiconductor industry and provide closer monitoring of toxicity tests in microbiology. In one step, this laser enables the two-sided characterization of surfaces and can be integrated into production chains. ...

Making the invisible visible

New method for studying atomic structures in material surfaces

21-May-2021 - Researchers from Friedrich Schiller University Jena, the University of California Berkeley and the Institut Polytechnique de Paris use intense laser light in the extreme ultraviolet spectrum to generate a non-linear optical process on a laboratory scale – a process which until now has only been ...

The light side of the Force: Creating a metal with laser light

The conversion to a metal only takes 20 femtoseconds

16-Feb-2021 - A group of researchers from the Fritz Haber Institute of the Max Planck Society and the Humboldt-Universität zu Berlin have found out that semiconductors can be converted to metals and back more easily and more quickly than previously thought. This discovery may increase the processing speed and ...

Optimal information about the invisible

How do you measure objects that you can't see under normal circumstances?

27-Jan-2021 - Laser beams can be used to precisely measure an object’s position or velocity. Normally, however, a clear, unobstructed view of this object is required – and this prerequisite is not always satisfied. In biomedicine, for example, structures are examined, which are embedded in an irregular, ...
