Abstract

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 with exceed in remanence magnetic field was obtained. This compact source is sufficiently intense for absorption spectroscopy.
