Abstract(in English) | We demonstrate the generation of continuous-wave terahertz radiation and apply this source to a molecular spectroscopy. The cw-THz radiation was generated by photomixing of two single-mode diode lasers in a low-temperature-grown GaAs photoconductive antenna. This source offers the output power of the order of 10 nW in the frequency range of 03-3 THz, and the linewidth of ~5 MHz, which is limited by the instability of the diode lasers. The transmission spectra of CO and CH_3CN molecules had been measured by using this source, and the 1 %-level absorption lines were clearly detected. The experimental results indicated that this source is useful for a high-resolution THz spectroscopy |
