Abstract
Frequency-resolved measurements of the emission of a collective free-electron laser operating at millimeter wavelengths have shown emission spectra that agree well 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.
