X-ray Laser Brings Gold Exploration to the Nanoscale

Pushing gold exploration to the nanoscale, scientists used SLAC's Linac Coherent Light Source X-ray laser to produce a series of 3-D images that detail a ringing effect in tiny gold crystals. The technique provides a unique window for studying why smaller is better for some specialized materials, including those used in chemical reactions and electronic components, for example.

X-ray Laser Brings Cellular Messengers into Focus

Last year's Nobel Prize in Chemistry – shared by Stanford School of Medicine Professor Brian Kobilka and Robert Lefkowitz of Duke University – recognized groundbreaking research in G protein-coupled receptors (GPCRs). GPCRs are embedded in cell membranes. They interact with signaling molecules outside of cells and trigger responses within cells.

Sharper Images for Extreme LCLS Experiments

An imaging technique conceived 50 years ago has been successfully demonstrated at SLAC's Linac Coherent Light Source, where it is expected to improve results in a range of experiments, including studies of extreme states of matter formed by shock waves.

X-ray Laser Pulses in Two Colors

SLAC researchers have demonstrated for the first time how to produce pairs of X-ray laser pulses in slightly different wavelengths, or colors, with finely adjustable intervals between them – a feat that will allow them to watch molecular motion as it unfolds and explore other ultrafast processes.

X-ray Laser Explores How to Write Data with Light

Using laser light to read and write magnetic data by quickly flipping tiny magnetic domains could help keep pace with the demand for faster computing devices.

Now experiments with SLAC's Linac Coherent Light Source (LCLS) X-ray laser have given scientists their first detailed look at how light controls the first trillionth of a second of this process, known as all-optical magnetic switching.

'Beam Sharing': Two Experiments with One X-ray Laser

Blue-glowing diamond crystals hold promise for expanding the research capacity of SLAC's X-ray laser by divvying up its pulses for use in separate, simultaneous experiments.

In a Feb. 6 test, scientists used perfect diamond crystals to separate ultrabright X-ray pulses at the Linac Coherent Light Source into groups of "colors," or wavelengths, for experiments spaced about 250 meters apart.

X-ray Laser Explores New Uses for DNA Building Blocks

The founding father of DNA nanotechnology – a field that forges tiny geometric building blocks from DNA strands – recently came to SLAC to get a new view of these creations using powerful X-ray laser pulses.

For decades, Nadrian C. "Ned" Seeman, a chemistry professor at New York University, has studied ways to assemble DNA strands into geometric shapes and 3-D crystals with applications in biology, biocomputing and nanorobotics.

An Impressive and Growing Array of Lasers at SLAC

In less than a decade, SLAC has built up an impressive array of dozens of laser systems – and a team of laser scientists and engineers – with capabilities that make it one of the most cutting-edge national laboratories under the U.S. Department of Energy.
