Abstract : The present invention is directed to a radiation source which produces electromagnetic radiation in the far-infrared range. For certain radar applications it is desired to use radiation in the far-infrared range. Conventional solid-state radiators cannot produce radiation in the far-infrared part of the spectrum, and in general, the prior art has not produced a source which can effectively operate in this range. It is therefore an object of the invention to provide a source which produces radiation in the far-infrared part of the spectrum down to the millimeter range. It is a further object of the invention to provide a source which can generate considerable power, and which can be efficiently cooled. It is still a further object of the invention to provide a source having a highly directional output. It is still a further object of the invention to provide a source which is pressure-tunable, field-tunable, and temperature-tunable.
