We report on the development of a high-peak-power, single-longitudinal-mode and tunable injectionseeded
terahertz-wave parametric generator using MgO:LiNbO
3, which operates at room temperature.
The high peak power (> 120 W) is enough to allow easy detection by commercial and calibrated
pyroelectric detectors, and the spectral resolution (< 5 GHz) is the Fourier transform limit of the subnanosecond
terahertz-wave pulse. The tunability (1.2 ‒ 2.8 THz) and the small footprint size (A3 paper,
29.7 × 42 cm) are suitable for a variety of applications.
