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.

Laser pulses—ultrashort bursts of coherent light—form the cornerstone of many modern optical technologies. Their interaction with matter, particularly in high harmonic generation (HHG), enables the ...

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 ...

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 ...

Researchers from Yokohama National University have developed a method to study how titanium's electron orientation and behavior influence its physical properties. Their findings, published in ...

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they ...
