| Outline of Final Research Achievements |
For fusion plasma diagnostics of large and high-density plasma devices, a new measurement system using a terahertz (THz) laser of the wavelength region of 50 μm is required. In this region between light and radio wave, measurement method including the light source has not been established. Therefore, we have surveyed THz laser lines, and the measurement method and components have been developed. It is important to realize the stable laser oscillation in order to improve reliability of the measurement system. In this study, we have developed the long-time stable 48- and 57-μm THz lasers pumped by a CO2 laser.
