In a conventional injection-seeded terahertz (THz) parametric generator (is-TPG), a complicated achromatic optical system controlling the angle of incidence of the seed beam is used to ensure tunability because both the pump and seed beams must satis

Abstract In this study, we propose a technique for identifying and imaging reagents through shielding over a wide dynamic range using a real-time terahertz (THz) spectroscopy system with multi-wavelength THz parametric generation/detection and machin

In this study, we developed a multi-wavelength terahertz-wave parametric generator that operates with only one injection seeding laser. Tunable lasers used as an injection seeder must be single-frequency oscillators, and conventional multi-wavelength

We achieved noise-free terahertz (THz)-wave output from an injection-seeded THz-wave parametric generator (is-TPG) employing high-power injection seeding. A conventional is-TPG uses a weak continuous-wave (CW) seed beam. The position in which broadba

In this study, noise-free THz-wave output from an injection-seeded THz-wave parametric generator (is-TPG) was achieved by high-power injection seeding. The THz signal and broadband noise originated from different positions in the LiNbO 3 crystal, and

We developed a high-power amplified spontaneous emission (ASE)-free fast wavelength-switchable external cavity diode laser (ECDL) using a digital micromirror device (DMD) as the wavelength selector. Generally, with a conventional fast wavelength-swit

In this work, we demonstrated real-time spectroscopy using a discreetly and fast wavelength tunable injection-seeded THz wave parametric generator (is-TPG). In our is-TPG, pump and seed beams shine the MgO:LiNbO3 crystal to generate the THz wave. At

We developed a fast wavelength switchable external cavity diode laser (ECDL) using a DMD as a seed laser for an injection-seeded terahertz (THz) wave parametric generator (is-TPG). Generally, the wavelength of an ECDL is selected by the angle of the
