High harmonic generation (HHG) is a highly non-linear phenomenon where a system (for example, an atom) absorbs many photons of a laser and emits photons of much higher energy, whose frequency is a ...

This Collection brings together original research on high harmonic generation, focusing on the underlying physical mechanisms and on the next generation of experimental setups. It also highlights the ...

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, ...

Nonlinear optics is a branch of optics that deals with the complex nonlinear relationships between the optical response of the medium and the incident light when it interacts with the optical medium.
