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 ...

Femtosecond laser pulses, with durations on the order of 10⁻¹⁵ seconds, have transformed the landscape of ultrafast optics by enabling the exploration of rapid light–matter interactions. The dynamics ...

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition rate. It is a mode-locked laser which uses light traveling within a ...

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 ...

The controlled generation of single photons is an essential element of numerous quantum technology applications, such as ...

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 ...

A 3D simulation of the wake behind the electron beam (purple) and how a light pulse (blue and red stripe) might surf behind it. The plasma wake is shown in alternating yellow for the absence of ...

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 ...

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 ...

"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 ...

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 ...

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 ...
