Abstract :
Our research focuses on the development and application of tunable THz-wave sources with high temporal and spatial coherence. Widely tunable THz-waves have been generated by the parametric-oscillation, parametric-generation, and difference-frequency-generation methods. Spectrum narrowing of the THz-wave to the Fourier transform limit has also been realized by introducing an injection seeding technique
