These ground-breaking innovations paved the way for all of the current ultra-bright fourth-generation light sources that are revolutionizing many fields of science, from biology to materials science.

International panel notes pioneering contributions in the field

LOS ALAMOS, N.M., Sept. 6, 2017—At an international science conference hosted recently in Santa Fe, N.M., Los Alamos National Laboratory scientists Bruce Carlsten, Dinh Nguyen and Richard Sheffield were awarded the 2017 Free-Electron Laser (FEL) Prize.

“The very brightest sources of x-rays are the latest generation of x-ray ‘light sources’ called free electron lasers," said Laboratory physicist Cris Barnes. “And those free electron lasers would be far less likely to exist and work without the pioneering contributions recognized by this year’s FEL Prize.” These ground-breaking innovations paved the way for all of the current ultra-bright fourth-generation light sources that are revolutionizing many fields of science, from biology to materials science.

The honor is an international recognition of key technologies that originally developed at Los Alamos in the 1980s and 1990s, such as the radio frequency photo-injector and high-brightness electron beams. These significant innovations also have enabled the x-ray free-electron laser (XFEL) facilities currently in use worldwide.

The honor called out three specific pioneering contributions:

  • the invention, first practical demonstration and theoretical understanding of the radio-frequency photo-injector, patented in 1985
  • the first practical demonstration of self-amplified spontaneous emission
  • the design and demonstration of the regenerative amplifier free-electron laser

Free-electron lasers involve techniques and materials central to the Los Alamos National Laboratory mission: X-rays are used to examine the inside of all materials, from living tissues to the parts in nuclear weapons. High-energy and very bright sources of x-rays provide the ability to penetrate deep into materials and provide very fast response to changing conditions.

Notably, this advanced light source technology is central to the Laboratory’s proposed future flagship experimental science facility, Matter-Radiation Interactions in Extremes (MaRIE).

Sponsored by Los Alamos, the International Free Electron Laser Conference, a five-day biennial conference held in Santa Fe, brought together an international perspective on recent advances in free electron laser theory, experiments, electron beam technology and applications of free-electron lasers. Nguyen and Carlsten served on the conference organizing committee. The FEL Prize Committee was composed of five members who work at institutions other than Los Alamos.
