| Outline of Final Research Achievements |
We demonstrated an injection-seeded terahertz-wave parametric generator (is-TPG) with capability of synchronization to other devices. A gain-switched laser diode as a pump source for terahertz-wave generation provided suppression of pulse jitter below 1 ns. The low time-jitter is-TPG demonstrated asynchronies spectrum sweep terahertz measurement with MEM-VCSEL as an injection seeder. This research project also studied photorefractive effect, suppression of phonon damping, and THz-wave generation based on DFG method for efficient optical to terahertz-wave conversion.

| Academic Significance and Societal Importance of the Research Achievements |
テラヘルツ波の利用・応用に関して今後ますます発展させるためには、これまでテラヘルツ波研究を先導してきたモノサイクルのテラヘルツ波だけでなく、光波領域同様に積極的な単色テラヘルツ波の利用が必要である。本成果は、マイクロチップレーザーを用いた従来方式では困難であった実験上の計測機器やスレーブ機器との同期を可能にしたことから、将来の応用展開に関する社会的意義は大きい。また、この成果の実現には、成果概要に記載した各種の新たな知見が活かされており、テラヘルツ波パラメトリック発生に関する学術的進展も得られた。
