Abstract

Terahertz time-domain spectroscopy has been an invaluable tool for non-destructive material testing and characterization tool for the evaluation of optical material parameters in the THz range. In this work, we designed and developed a 1.55 Î¼m femtosecond fiber laser-based terahertz transmission time-domain spectroscopy setup (THz-TTDS) suitable for the extraction of refractive index and absorption coefficient. As a proof-of-concept demonstration of the efficacy of the system, we have measured the frequency-dependent refractive index and absorption coefficient of a 1.0 mm glass. Our results report on a compact and portable system suitable for determing the THz refractive index and absorption coefficient of materials.
