The generation and observation of high-power, coherent, far- infrared undulator radiation from sub-picosecond electron bunches at the SUNSHINE facility is reported. Coherent undulator radiation tunable from 50 to 200 μm wavelength is demonstrated. Measurements of the energy (up to 1.7 mJ per 1 μs macropulse), frequency spectrum, and spatial distribution of the radiation are reported. Apparent exponential growth of the radiated energy as a function of undulator length is observed.
