| Popis: | For the limited power capacity problem of single photoconductive antenna,we use photoconductive antenna power combining technology to research high power and ultra-broadband terahertz radiation. By constructing a power combining system of three-way photoconductive antenna,using500 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 improved efficiently. |
