ABSTRACT: Using THz time-domain spectroscopy, the home-grown organic crystal DAST and widely used high-efficient ZnTe were characterized as THz emitters. Bolometer was also used to measure the absolute energy of THz radiation from DAST and ZnTe. The refractive index and absorption coefficient of DAST were measured too. It is concluded that the home-grown DAST is a kind of high-efficiency THz material, and could become a good THz emitter and detector after the improvement in growing process.
