Tripling the energy and refining the shape of optical laser pulses at LCLS’s Matter in Extreme Conditions instrument allows researchers to recreate higher-pressure conditions and explore unsolved questions relevant to fusion energy, plasma physics and materials science.

Extraordinarily precise measurements -- within millionths of a billionth of a second and a billionth of a hair's breadth -- show this ‘electron-phonon coupling’ can be far stronger than predicted, and could potentially play a role in unconventional superconductivity.

A new X-ray laser technique allows scientists to home in on these single-electron triggers to better understand organic molecules that respond to light, including receptors in your eyes, plastic products and DNA building blocks that need to protect themselves from...

Researchers at SLAC are already looking at the largely unexplored realm of attosecond science.

Ryan Coffee, scientist at the Linac Coherent Light Source, explains in a video interview.

Physicist Phil Bucksbaum gives a brief introduction to Femtosecond Week at SLAC.

SLAC celebrates five days of ultrafast science.

Join us for five days of ultrafast science from April 17 to 21.

SLAC experiments demonstrate a new way to access valence electrons, which are important in forming chemical bonds and determine many of a material’s properties.

More than 40 interns spent 10 weeks this summer helping SLAC researchers advance the use of the Linac Coherent Light Source.

Understanding how a material’s electrons interact with vibrations of its nuclear lattice could help design and control novel materials, from solar cells to high-temperature superconductors.

Just as Schroedinger's Cat is both alive and dead, an atom or molecule can be in two different states at once. Now scientists have exploited this behavior to make X-ray movies of atomic motion with much more detail than ever...
