Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

Scientists at the University of Oxford have unveiled a pioneering method for capturing the full structure of ultra-intense laser pulses in a single measurement. The breakthrough, published in close ...

Scientists have developed a groundbreaking technique called RAVEN that can capture the full complexity of an ultra-intense ...

Scientists can now snap ultra-powerful laser pulses in one shot. RAVEN reveals distortions instantly, unlocking breakthroughs ...

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition ...

The 2018 Nobel Prize in Physics was announced this morning "for groundbreaking inventions in the field of laser physics." This is really two half-prizes, though: one to Arthur Ashkin for the ...

Crucially, the laser pulse is so short that it comprises less than one cycle of the light (about 2 fs). This ensures that the emitted electron pulse is not buffeted around by an oscillating electric ...

But getting to 10 25 W/cm 2 is tough. The issue is one of material. Or, rather it's the lack of a material that can survive long enough to focus the laser light. This is where plasma mirrors come in.

An ultrashort-pulse laser being developed by the Army has more in common with Star Wars blasters than the continuous-wave laser weapons currently used. It fires a stream of self-focusing bullet ...

Scientists have generated the world fastest laser pulse, a beam that shoots for 67 attoseconds, or 0.000000000000000067 seconds. Skip to main content. SECURITY. POLITICS. THE BIG STORY.
