Abstract

A Terahertz Time-Domain Spectroscopy (THz-TDS) system with electro-optical detector based on a ZnTe crystal is presented. The pump laser is a Ti:Sa laser with pulse duration of approx. 10 fs at a central wavelength of 800 nm. Using an optimized detection configuration, a signal-to-noise ratio better than 103 is achieved, applying an optical laser power of only 25mW. Several substances can be clearly distinguished on the basis of their specific THz absorption spectra.
