Abstract
A tunable wideband coherent source comprising a laser source and a microwave source, means for combining and mixing the outputs of the laser and microwave sources so as to provide a combined output, and means for filtering the combined output so as to separate sum and difference components, with any undesired background being suppressed. Our source may be used with means for utilizing the sum signal, the difference signal, or both of these.
