New p - Ge THz laser spectrometer for the study of solutions:THz absorption spectroscopy of water
We present the development of a high power, tunable far-infrared p -germanium laser spectrometer for the study of dissolved biomolecules in the THz range. As a first application we report on the measurement of the absorption coefficient α for liquid water in the frequency range from 81 to 96 cm − 1...
