摘要： A first laser beam 1a and a second laser beam 1b are incident on a difference frequency mixing unit, and the two laser beams are overlapped in the difference frequency mixing unit, thereby generating a terahertz wave whose frequency is a frequency difference between the two laser beams. Each laser beam has a spatial spread in a frequency gradient direction, and a spatial frequency distribution of each laser beam is a distribution in which a magnitude of a frequency gradually increases in the frequency gradient direction. Accordingly, a frequency difference between the two laser beams is equal in each position in an overlapping region of the two laser beams. A terahertz wave of a single frequency is generated from this overlapping region. By spatially shifting the first laser beam and the second laser beam with respect to each other in the frequency gradient direction, the frequency difference in the overlapping region is changed, so that the single frequency is changed.
摘要翻译：第一激光束1a和第二激光束1b入射在差频混合单元上，并且两个激光束在差频混合单元中重叠，由此产生太赫兹波，其频率是两个激光束之间的频率差。每个激光束在频率梯度方向上具有空间扩展，并且每个激光束的空间频率分布是其中频率的幅度在频率梯度方向上逐渐增加的分布。因此，两个激光束之间的频率差在两个激光束的重叠区域中的每个位置处相等。从这个重叠区域产生单一频率的太赫兹波。通过在频率梯度方向上使第一激光束和第二激光束在空间上彼此相对移动，重叠区域中的频率差被改变，使得单个频率改变。

摘要： The invention relates to a method and a device for generating electromagnetic radiation in the terahertz and millimeter range, using a non-linear medium generating the indicated radiation by differential frequency generation within the laser resonator of a suitable laser, such as a VECSEL or a disc laser operating in two or more color modes. The invention further relates to novel decoupling structures used to this end for optimized decoupling and separating of the generated radiation from the optical radiation generated in the laser resonator, and suitable novel non-linear media as such.

摘要： The invention relates to an integrated antenna for the emission or reception of terahertz radiation, characterised in that it comprises: a conductive ground plane (PM) deposited on a surface (S) of a dielectric or semiconductor substrate (SB); a conductive ribbon (RC) extending above the ground plane (PM) and forming an angle ( ) therewith in such a way as to form a horn-shaped radiating structure (SR) with electromagnetic transverse waves; and a planar wave guide (G) comprising at least one first conductive strip (BC1) and one second conductive strip (BC2) which are formed on the surface of the substrate and each linked to the conductive ribbon (RC) and to the ground plane (PM). The invention also relates to a terahertz emitter/receiver comprising such an antenna and a device for generating and/or detecting a terahertz signal, said device being built into the same substrate (SB) as the antenna and connected to the latter by the wave guide (G). The invention also relates to the production of such an antenna and to such an emitter/receiver.
