Researchers Observe Superradiance In A Free Electron Laser

At the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, a team of researchers has generated extremely short light pulses using a new technique that could be used in the next generation of light source facilities around the world to catch molecules and atoms in action. Published on January 19, 2007 in Physical Review Letters, the research team’s findings describe the use of a laser to control the pulse duration of light from a free electron laser (FEL), a type of light source with a brightness up to one billion times higher than that of ordinary synchrotron light. The team also reports the first experimental observation of a phenomenon called superradiance.
