| Research Abstract |
We have developed the high-power THz time-domain spectroscopy using the high-power THz source on the basis of the compact electron linac. The high-power THz wave has been generated using coherent transition radiation (CTR) with polarization control for THz time domain spectroscopy (THz-TDS) with the S-band compact linac at AIST. The THz-CTR-TDS System has been constructed with EO sampling method. As a result, the THz temporal waveform has been successfully measured with this system. In near future, we will perform the single-shot measurement with a chirped probe laser in order to improve the stability of this system and to extend the measured spectral range.
