摘要：
Chirped-pulse spectroscopy combined with single-shot electro-optic (EO) sampling enables to detect terahertz waveform in time-domain without scanning the relative time delay between the terahertz wave and the probe pulses. In this study, we demonstrate reduction of the waveform distortion appeared in the chirped-pulse spectroscopy by combining sum-frequency generation and dispersion compensation. In addition, by performing the phase offset EO sampling, the positive and negative phase offset signals were measured simultaneously to reduce the common mode noise. As the result, single-shot terahertz waveform detection with a +/- 50 V/cm accuracy was achieved.
