ABSTRACT:
A coherent optical source, having a center frequency in the terahertz band can be generated. Two coherent optical sources of different frequencies can be mixed in a nonlinear crystal to generate an optical source having a third distinct frequency in the terahertz frequency range. The third frequency, an idler frequency, equals the difference between pump and signal wave frequencies incident on the crystal. The pump and signal wave frequencies are selected so that their frequency difference is in the terahertz range and so that the interaction between the pump, signal, and idler wave frequencies is phase matched using a cross-Reststrahlen band dispersion-compensated phasematching technique.
