Abstract

Generation of electromagnetic or other waves of any frequency, coherence, modulation, power, etc. and for scaling such waves in frequency by any factor. Generation is achieved by incorporating an available source of desired coherence, modulation and power properties at some band of frequencies and scaling to the desired frequencies. For scaling, a source-distance dependent mechanism of copending applications titled 'Passive distance measurement using spectral phase gradients' and 'Distance-dependent spectra with uniform sampling spectrometry', which depends solely on source linespread and wave propagation, and is independent of specific material properties, is combined with a means of determination, or prior knowledge, of the source distance. This distance, from the source to the frequency scaling mechanism, may be shortened with a refractive or dispersive medium, or varied for fine tuning of the frequency scale factor, and its variation may be effected via electrooptic or magnetooptic properties of the medium.
