Abstract

We report on measurements of transmission spectra of chosen materials (Hexogen, sugar, L-tartaric acid, 4-aminobenzoic acid) in the range 0.7-2.0 THz. The measurements were carried out by means of a setup, which bases on the optical parametric oscillator (OPO) combined with the hot electron bolometer (HEB). The setup consists of the commercially available tunable OPO working in the range 0.7-2.0 THz with repetition rate 53 Hz, duration of the impulse of about 20ns and energy 10nJ. The beam was detected by the fast and sensitive HEB. The spectra were compared to results obtained from a standard time domain spectroscopy (TDS) setup. Only small discrepancies between spectra measured by both methods are observed. For the range 0.7-2.0 THz typical features can be identified using both methods. Above 2 THz the TDS setup seems to have better performance in terms of signal-to-noise ratio and sensitivity.
