| Outline of Final Research Achievements |
Sub-THz frequency of the electromagnetic wave is a region where high power sources or sensitive detectors are insufficient even though sub-THz wave would be applicable to non-destructive imaging, remote sensing or measurements in fundamental physics such as the optical Hall effect. In this research, I developed the tunable sub-THz wave source using nonlinear photonics by pumping a nonlinear crystal of DAST. The DAST crystal was pumped by the originally developed injection seeded dual-wavelengths infrared source. It was also demonstrated by the sub-THz wave source that the non-destructive imaging of internal structure of a sample and spectrum imaging of a sample were possible. It is expected that further applications in spectrum imaging or remote sensing to various materials utilizing high transmission of sub-THz wave.
