Outline of Final Research Achievements |
Feedback control of terahertz-wave generation and detection system was studied in terms of electronics. We found novel methods to introduce the feedback circuit in the terahertz-wave measurement system, based on the intensity modulation of terahertz waves. Using nonlinear optical effect for upconversion (stimulated Raman effect), terahertz-wave detection of minimum pulse energy of 2 aJ/pulse, therefore the dynamic range of 110 dB, was successfully achieved.
