针对单个光导天线功率容量有限的问题，采用光导天线功率合成技术研究高功率、超宽带的太赫兹辐射方法。通过构建三路光导天线功率合成系统，以500μm孔径的偶极子光导天线为对象，进行了功率合成技术研究。结果表明：当三路500μm孔径的偶极子光导天线产生太赫兹的光程差一致时，合成后的时域光谱峰值最大，时域相干度达90.6%，提高了太赫兹输出的功率。

For the limited power capacity problem of single photoconductive antenna, we use photo-conductive antenna power combining technology to research high power and ultra-broadband terahertz radiation. By constructing a power combining system of three-way photoconductive antenna, using 500 μm aperture dipole photoconductive antenna as the object, we studied the power combining technology. When the optical path differences of terahertz emitted by three-way 500 μm aperture photoconductive dipole antenna are the same, the power combined time-domain spectral reaches to maximum peak, the degree of temporal coherence up to 90. 6%, the output power of terahertz is im-proved efficiently.
