Electrons determine everything: how chemical reactions unfold, how materials conduct electricity, how biological molecules transfer energy, and how quantum technologies operate. But electron dynamics ...

High harmonic generation (HHG) is a powerful nonlinear optical process whereby intense laser pulses interact with matter, resulting in the emission of light at multiples of the fundamental frequency.

ICFO researchers have set a new record by generating the shortest soft X-ray pulse to date –just 19.2 attoseconds long. This ...

Scientists discover how a hidden crystal pattern in advanced materials can control how they emit light, offering new ways to guide ultrafast signals using lasers. (Nanowerk Spotlight) Modern ...

As demand for next-generation chips intensifies, high-harmonic generation (HHG) is becoming fundamental in semiconductor research and development. Erik Hosler, a specialist in semiconductor processes, ...

The study of processes occurring at attosecond timescales utilizing extreme ultraviolet (XUV) pulses is at the forefront of ultrafast science. These XUV pulses, produced via high-harmonic generation ...

ICFO researchers have achieved a remarkable milestone by producing the shortest soft X-ray pulse ever recorded, measuring just 19.2 attoseconds in duration.

Liquids and solutions are complex environments—think, for example, of sugar dissolving in water, where each sugar molecule becomes surrounded by a restless crowd of water molecules. Inside living ...
