Atomic X-ray Laser Blasts Ahead
A femtosecond-pulsed, atomic X-ray laser—beaming at the highest energies reached so far by its kind—could enable new developments in high-resolution spectroscopy, according to a report in Nature (DOI: 10.1038/nature10721). X-ray lasers have been in use since the 1980s, but scientists are forever in search of higher energy, shorter-pulsed, and more coherent beams to probe the atomic-scale distances and motions of molecules. . . .
