Abstract
We have observed radiation from a waveguide mode free electron laser u sing coherent synchrotron radiation emitted from electron bunches. The radiation was observed at 2.73 mm with a line-width of 0.4%. This spe ctral selection was attributed to the dispersion of the radiation in t he waveguide. We found that the radiation had to have a group velocity equal to the velocity of the electrons passing through the wiggler fi eld.
