According to the abstract released by the U.S. Patent & Trademark Office: "A terahertz wave generator includes a femtosecond pulse light source 1 that outputs a near-infrared light L.sub.1, which is a pulse light, a diffraction grating 2 that diffracts the outputted near-infrared light L.sub.1, an optical system including a lens 3 and a lens 5, and a LiNbO.sub.3 crystal 6 for generating terahertz waves L.sub.2 with irradiation of the near-infrared light L.sub.1. The optical system including the lens 3 and the lens 5 is arranged such that at least a pan of a plane S.sub.0' optically conjugated to a diffractive plane S.sub.0 of the diffraction grating 2 is formed within the LiNbO.sub.3 crystal 6, and a direction normal to the conjugated plane and a direction normal to a plane formed by the pulse front of the non-linear L.sub.1 are matched with each other within the LiNbO.sub.3 crystal 6. This makes it possible for the near-infrared light L.sub.1 to cause the nonlinear optical effect to efficiently occur in the wide range, whereby high-efficient and high-power terahertz waves can be obtained."

The Patent was filed on March 8, 2011 under application No. 20130075629
