Paper Abstract

Semiconductor based terahertz sources and lasers allow applications in biomolecular spectroscopy and imaging. We present typical experimental set-ups to study liquid and water samples. Water has a very high absorption coefficient in the THz spectral range. It can be measured in transmission if a high signal-to-noise ratio is available otherwise by reflection measurements. We show THz imaging examples of dried lactalbumin drops and a THz spectrum of a thin film of the nucleobase guanine.
