Abstract

Recordings of rare events require detection strategy in single-shot. It is also of crucial interest for recordings of terahertz waveforms in terahertz spectroscopy of irreversible processes. The time-domain spectroscopy usually requires scanning techniques that prevent the applications of very low repetition rate sources such as strong THz pulse sources based on table-top high power lasers or accelerators. We present a strategy allowing complex electric fields to be recorded in single-shot using the chirped pulse electro-optic sampling technique at 1550 nm with signal processing techniques based on DEOS (Diversity Electro-Optic Sampling).
