Scientists develop new metasurfaces for deep UV-imaging

Russian researchers have developed a new material that converts infrared light to ultrashort pulses of ultraviolet. For this purpose, the scientists exposed silicon film to a laser so that its relief adjusted under the light ...

Why cryptophyte algae are really good at harvesting light

In an algae-eat-algae world, it's the single-celled photosynthetic organisms at the top (layer of the ocean) that absorb the most sunlight. Underneath, in the sublayers, are cryptophyte algae that must compete for photons ...

Catching proteins in the act

Some of the fastest processes in our body run their course in proteins activated by light. The protein rhodopsin sees to it that our eyes can rapidly take in their ever-changing surroundings. Free-electron X-ray lasers such ...

Attosecond camera for nanostructures

Physicists based at Ludwig-Maximilians-Universitaet (LMU) in Munich and the Max Planck Institute for Quantum Optics have observed a nanoscale light-matter phenomenon which lasts for only attoseconds.

Attosecond physics: A switch for light-wave electronics

Light waves could in principle be used to drive future transistors. Since the electromagnetic waves of light oscillate approximately one million times in a billionth of a second, i.e. at petahertz (PHz) frequencies, optoelectronic ...
