15 Aug 2011 An international team of researchers spanning Australia, North America, and Europe has created a model for a new kind of attosecond laser

An attosecond is a millionth of a picosecond, or 10 −18 of a second. Light travels 0.3 nanometers in an attosecond, which is roughly the spacing between atoms in a solid.

They really need to think a bit more before making A research team has demonstrated a 53-attosecond X-ray flash, opening the door to shoot slow-motion video of electrons and atoms in living cells. Your source for the latest research news A research team at the University of Central Florida has demonstrated what it calls “the fastest light pulse ever developed”, a 53-attosecond X-ray flash.

With a flash of light to stimulate an electron and attosecond x-ray flashes to follow its activities, scientists could directly observe such phenomena as an atom becoming ionized, or the bonding of two or more atoms into molecules. Sound like a technology for the far-distant future?

A laser light shines in a gas cell where UCF researchers generate attosecond pulses. Courtesy: UCF. Studies of ultrafast processes could become more widely accessible thanks to researchers at the University of Central Florida (UCF) in the US, who have shown that commercially available, industrial-grade lasers can generate attosecond pulses of light.

Attosecond explained.. What I’m hearing is “I don’t know how to turn this off please kill me” Still shorter pulses belong to the attosecond regime - the regime wherein a University of Central Florida research team is creating optical pulses sufficiently brief to stop quantum mechanics in With a flash of light to stimulate an electron and attosecond x-ray flashes to follow its activities, scientists could directly observe such phenomena as an atom becoming ionized, or the bonding of two or more atoms into molecules. A research team has demonstrated a 53-attosecond X-ray flash, opening the door to shoot slow-motion video of electrons and atoms in living cells. An international group of physicists and engineers, led by Professor Zenghu Chang of the University of Central Florida, has produced the shortest-ever laser pulse: a 53-attosecond X-ray flash.

000. 00 An attosecond is 1×10 −18 of a second (one quintillionth of a second). For context, an attosecond is to a second what a second is to about 31.71 billion years. The word "attosecond" is formed by the prefix atto and the unit second. Attosecond pulses were first demonstrated in 2001. Since then researchers around the world have been trying to make ever-shorter pulse durations because of the door they could open to understanding Flash took an action in a singular picosecond, regardless of whether it was the entire disabling of the gun, or just smashing the chip.

Nonlinear attosecond spectroscopy Research project The shortest pulses ever created last only 100 attoseconds (10^-16 s), which is the temporal scale of electrons and allows to measure electron motion in atoms and molecules.

Attosecond camera for nanostructures. Physicists of the Laboratory for Attosecond Physics at the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität Munich in collaboration with scientists from the Friedrich-Alexander-Universität Erlangen-Nürnberg have observed a light-matter phenomenon in nano-optics, which lasts only attoseconds. attosecond light field transients spectrally spanning over 1.5 to ~2 octaves, from the deep ultraviolet (DUV) to near infrared (NIR), and to harness attosecond sci- ence by their unique properties.
