Abstract:

We have developed a THz-wave spectrometer with the combination of a bright THz-wave source of THz-wave parametric generator TPG and a Martin- Puplett interferometer. The TPG output was optimized by studying various configurations with LiNbO3 crystals. THz-waves which span the 1-2THz region were emitted with the peak power of 280 micro W. The whole system, including the nitrogen-purge unit, was constructed in a table-top size. By use of the THz-wave spectrometer, absorption lines of water vapor were successfully obtained.
