We developed a Nd:YAG multi-mode laser-pumped injection-seeded terahertz-wave parametric generator (is-TPG), and compared its terahertz (THz)-wave output energy to that of a single-mode laser-pumped is-TPG system. The oscillation threshold of the multi-mode is-TPG was approximately 73% lower than that of the single-mode system, and the multi-mode system produced higher THz-wave energy than that of the single-mode system with the same pump energy. The required seed power for the multi-mode system was much lower than that for the single-mode system. The multi-mode laser was compact, inexpensive, and simpler to handle than a single-mode device. This resulted in a room-temperature THz-wave generation system that could produce sufficient power for THz spectroscopy.
