Description

A single-shot terahertz time-domain spectroscopy method is developed using an echelon-pair. Terahertz waveform is encoded to a beamlets array by electro-optic effect, with a total time window of 37.7 ps and a time step of 94.3 fs. Comparing with spectral encoding methods, this technique directly encodes terahertz waveform to spatial resolution, which is more suited as a terahertz diagnosis for high power ultra-short laser systems with inherent spectral fluctuations.
