Scientists Take a Major Step Toward Smaller, Cheaper Free-Electron Lasers

Researchers take a step toward smaller, more affordable free-electron lasers. Scientists studying atoms, molecules, and new materials use light a little like a photographer uses a camera flash, illuminating their subjects with extremely brief, intense bursts. These flashes come from machines called free-electron lasers, or FELs, and demand for experiments at the large facilities that [...]
