Free-electron laser (FEL) research is continuing; experimental configurations already exist and further modifications are being planned. The Livermore/Berkeley collaboration has announced a 35-GHz amplifier with high gain and efficiency. A team at the University of California, Santa Barbara, is employing a single-particle or Compton interaction instead of the intense Raman effects beam. In the United Kingdom, there is the Heriot Watt-Glasgow-Daresbury collaborative FEL project attempting to obtain laser oscillation above threshold at 10.6 microns with a wide tuning range. Apart from the UK project, almost all funded FEL research is now concentrated in the United States.
