Study of Gain, Bandwidth, and Tunability of a Millimeter-Wave Free-Electron Laser Operating in the Collective Regime.
Abstract
Frequency-resolved measurements of the emission of a collective free-electron laser operating at millimeter wavelengths have shown emission spectra that agree with theoretical predictions for the collective free-electron laser instability. Broad tunability, moderate emission linewidths, and high single frequency gain have been observed. In addition, adjusting the axial field in the end region of the interaction has been found in some cases to cause a large increase in measured power and efficiency. (Author)
