Abstract
We demonstrate real-time and ultrabroadband THz time-domain spectroscopy in a compact optimized system. The system is based on a femtosecond fiber laser at 1560 nm as pump source and optical rectification and detection in organic electro-optic DSTMS crystals. Terahertz time-domain spectroscopy with a spectrum extending beyond 20 THz with a maximum bandwidth 70 dB has been reached with this system. We present spectroscopic measurements of various biomedical and pharmaceutical substances in transmission and reflection geometry at frequencies up to 20 THz.
