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 ...

Ultrafast laser pulses, typically defined by durations in the femtosecond to picosecond range, have revolutionised both fundamental science and applied technology. Their generation and amplification ...

Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort X-ray pulses at the X-ray free-electron laser SwissFEL. This achievement ...

Representation of domain walls within a ferromagnetic layered material. New research shows that when these materials are hit with a free electron laser, magnetic domain walls move much faster than ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

"Within femtoseconds, the laser pulse excites the electrons in the material. Several picoseconds later, the excited electrons transfer their energy to the atomic nuclei." Consequently, this energy ...

For the first time, researchers at Umeå University, Sweden, have demonstrated the full capabilities of their large-scale laser facility. The team reports generating a combination of ultrashort laser ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special technique to film laser light in real time, researchers observed how ...

Ultrashort laser pulses—that are shorter than a millionth of a millionth of a second—have transformed fundamental science, engineering and medicine. Despite this, their ultrashort duration has made ...

Shanghai scientists develop ultranarrow bandwidth mode-locked laser with a widely-tunable pulse duration. Shanghai’s ultranarrow bandwidth mode-locked laser. Click for info. Ultranarrow bandwidth mode ...

If there’s one lesson to be learned from [Aled Cuda]’s pulsed laser driver, it’s that you can treat the current limits on electronic components as a suggestion if the current duration is measured in ...
