Abstract

The research of ultrafast dynamic processes needs the support of synchronization technology in the corresponding time scale. To use the THz pulse of China Academy of Engineering Physics Terahertz Free Electron Laser (CTFEL) and an external fs laser to study the ultrafast dynamic process with pump-probe technique needs the femtosecond-level synchronization between the two pulses. This letter introduces previous work and feasibility study of the synchronization method between THz and fs laser and obtains some experimental data for constructing the feedback compensation system. The experiment generates THz pulses by BNA/ZnTe crystal acting as accelerator-based THz light source for simulation, another fs laser pulse (split from the same fs laser, having a delay line to get different timing jitter.) will be modulated and detected to get the characterization using electro-optical sampling (EOS) and sum-frequency generation (SFG) and detection to give the feedback parameter.
