Abstract:
Apparatus and method for high-power multi-function millimeter-wavelength (THz-frequency) signal generation using OPO and DFG in a single cavity. In some embodiments, the OPO-DFG cavity includes an optical parametric oscillator (OPO) non-linear material that receives pump light I P  having pump-light frequency and generates two different lower intermediate frequencies of light—an OPO-signal beam I S  and a spatially/temporally overlapping OPO-idler beam I I . A difference-frequency generator non-linear material then receives the two intermediate-frequency beams I I  and I S , and the DFG then generates a THz-frequency output signal that has a frequency equal to the difference between the two intermediate frequencies. In some embodiments, a single-piece crystal of non-linear material is used for both OPO and DFG functions. Some embodiments use a bow-tie ring having four mirrors that define the optical path: an I P -beam-entry mirror, an I P -light-extraction mirror to remove unconverted I P -beam, an I I -beam-extraction mirror, and an I S -beam-extraction mirror, and a fifth I THz -beam-extraction mirror.

Claim (Index 10):
The method of  claim 1 , wherein the generating of the gigahertz-terahertz-range signal includes passing the light of the two intermediate frequencies through a non-linear optical crystal that acts as a difference frequency generator.
