Abstract	:	The far infrared region of the electromagnetic spectrum, 15-3000 pm in wavelength,has a paucity of narrow band laser sources. To address the issue of whether a gratingbased free electron laser could operate well as such a source, a grating loaded waveg-uide of variable length, driven by a 2.3 MeV electron beam, was modeled, built, andtested, with the expectation of observing gain. Data was collected in the form ofpower spectra from a Fabry-Perot interferometer. Emission was observed for wave-lengths between 0.30 mm and 3 mm, and there was very good agreement betweenthe theoretical predictions for wavelength and the observed wavelengths. Gain wasobserved to agree with theoretical predictions to within a factor of 10 for wavelengthslonger than 1 mm, but was between 10 and 100 times greater than predicted gain forshorter wavelengths. Overall emitted power agreed reasonably well with theoreticalpredictions, but observed power per wavelength was higher than predicted power forwavelengths shorter than 1.5 mm.tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
