| Outline of Final Research Achievements |
Widely tunable THz-wave generation based on difference frequency generation and THz-wave up-conversion detection were demonstrated. As extending to lower frequency generated by DFG method, injection-seeding technique was applied. THz-wave generation with the tunability from 0.3 THz to 4 THz was demonstrated. To improve the signal/noise ratio for spectroscopic measurement, sensitive up-conversion detection was also demonstrated. As a result, minimum detectable THz-wave energy was 100 aJ/pulse, which was exceeding cryogenically cooled Si-bolometer.
