Optical Synchronization Systems for Femtosecond Light Sources IB-2131

by

APPLICATIONS OF TECHNOLOGY:

  • Short pulse free-electron laser experiments
  • Short pulse laser or fast event experiments over long distances
  • Phased array radar or radiotelescopes with long baselines
  • Ultra high speed telecommunications (fiber optics)
  • Transmission of time signals for precise ranging, as in LIDAR (Light Detection and Ranging) or ultra-precise GPS-like positioning

ADVANTAGES:

  • Stabilizes glass fiber down to the femtosecond level
  • Uses currently available technologies

ABSTRACT:

Berkeley Lab scientist Russell Wilcox and scientists at Menlo Systems GmbH have developed a system for synchronizing two modelocked pulsed lasers to within ten femtoseconds. The invention enables synchronizing signals to be trasnmitted over standard fiber optic lines to a precision previously unavailable. The technology uses currently available technologies in an novel way. To see a recent publication on this technology please click on the link below.
