Abstract

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

using 500 m 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 m 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.
