利用飞秒光纤激光器作为激励源，设计了一种新型的2 T永磁体，实现了InAs半导体结构的THz辐射源。通过采用新设计的磁路，获得了一种结构紧凑、能超越剩磁的永磁体。这种紧凑的光源对于吸收光谱学来说足够强。
A compact THz-radiation source using an InAs semiconductor is demonstrated with a turn-key femtosecond fiber laser as an excitation source and a newly designed 2 T permanent magnet. By using a newly designed magnetic circuit, a compact permanent magnet which can exceed the remanence magnetic field was obtained. This compact source is sufficiently intense for absorption spectroscopy.
