Scientists from the Lawrence Berkeley National Laboratory (Berkeley Lab) have generated 300-femtosecond pulses of bend-magnet synchrotron radiation at the Advanced Light Source (ALS) with the aid of a laser ''time-slicing'' technique. This technique allows an ultrashort portion of an electron bunch in the ALS storage ring to be spatially displaced in such a way that the synchrotron radiation from the displaced portion can then be collected separately. Their proof-of-principle experiment demonstrates that this technique is a viable one for producing ultra-short pulses of x-rays. An ALS bend-magnet beamline is already under construction that will be dedicated to time-resolved x-ray diffraction, EXAFS, and other techniques capable of probing the long-range and local structure of matter on a femtosecond time scale. A proposed undulator beamline based on the same technique would further enhance the flux and brightness by orders of magnitude.
