Abstract
We have observed the oscillation of a waveguide mode free-electron las er using the coherent synchrotron radiation emitted from electron bunc hes. The oscillation was observed at 2.73 mm with a linewidth of 0.4%. This spectral selection was attributed to the dispersion of the radia tion in the waveguide. We found that the oscillating radiation had to have the same group velocity as the velocity of the electrons passing through the wiggler field.
