Abstract :
We report on the development of a widely tunable (frequency: 0.6-2.6 THz), injection-seeded THz-wave parametric generator (is-TPG), which operates at room temperature. The spectral resolution (<100 NfHz, 0.0033 cm-1) is the Fourier transform limit of the nanosecond THz-wave pulse. The continuous scanning and narrow spectral bandwidth of the is-TPG were verified in the absorption spectrum of low-pressure water vapor.
