Abstract

We report on the development of a high-peak-power, single-longitudinal-mode and tunable injection-seeded terahertz-wave parametric generator using MgO:LiNbO3, 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 (< 10 GHz) is the Fourier transform limit of the sub-nanosecond 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.

(left) Dispersion relation of the polariton, an elementary excitation generated by the combination of a photon and a transverse optical phonon (ωTO). The polariton in the low-energy region behaves like a photon at terahertz frequency. Due to the phase-matching condition as well as the energy conservation law, both of which hold in the stimulated parametric process, the tunable terahertz-wave is obtained by the control of the wave vector kT. (right) Noncollinear phase-matching condition using MgO:LiNbO3.

Wavelength and linewidth of the terahertz-wave measured with a scanning Fabry–Perot etalon consisting of two metal mesh plates. (a) The stability of the spectrum is demonstrated and the displacement between the two periods (220 μm) corresponds directly to the wavelength. (b) The FSR of the etalon is 12 GHz and the linewidth of the terahertz wave is measured to be less than 5 GHz.
