A Sharp New Eye to View Atoms and Molecules
Physicists long dreamed of producing X-ray laser pulses that probe matter at the level of atoms and molecules. Scientists realized this dream in 2009 with the hard X-ray free-electron laser at the Linac Coherent Light Source (LCLS). But each LCLS X-ray pulse has a slightly different intensity and wavelength distribution. A new oscillator design overcomes these problems with an approach inspired by optical lasers.
