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 {mu}m wavelength is demonstrated. Measurements of the energy (up to 1.7 mJ per 1 {mu}s 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. {copyright} {ital 1996 American Institute of Physics.}
