Motivation for Free Electron Laser Experiments
 

'Free-electron lasers represent an altogether new and exciting class of coherent optical sources. Making use of a simple and elegant gain medium - an electron beam in a magnetic field - they have already demonstrated broad wavelength tunability and excellent optical-beam quality. For the future theyoffer the possibility of generating the greatest focussed power ever achieved by a laser. But even before this is achieved, the unique advantages of free-electron lasers, especially their tunability, will make them useful for a variety of important applications in science and medicine.' (Professor Charles A. Brau, Director of the Vanderbilt FEL.)

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE’s Office of Science by Brookhaven Science Associates, a limited-liability company founded by Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
