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 ...

A research team in Kiel has demonstrated a previously unknown effect in graphene—a single layer of carbon atoms whose discovery earned the 2010 Nobel Prize. For years, graphene has been seen as a ...

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 ...

Muons are unstable subatomic particles that spontaneously and rapidly transform into other particles via a process known as electroweak decay. Altering the speed with which muons decay into other ...

A peek inside the record-breaking laser. The image shows the round amplifier disk, through which the laser beam passes several times (bright spot at the centre). The word laser usually conjures up an ...

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 ...

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 ...

"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 ...

There has been vivid interest in laser electrochemical phenomena and applications. Laser-induced electrochemical deposition of metals on metals relies possibly on thermal and defect generation effects ...
