Single-shot electro-optic sampling of THz waveforms using chirped laser pulses

We present recent strategies allowing THz pulses to be recorded in single-shot, using chirped pulse electro-optic sampling. We show in particular that high repetition rates (typically 1-100e6 TDS traces per second) can be obtained using an association of electro-optic sampling with the so-called time-stretch technique. We also present recent results demonstrating that reaching simultaneously high bandwidth and high frequency resolution (i.e., long recordings) is possible with these single-shot systems, using a variant called called Diversity Electro-Optic Sampling (DEOS). Applications to studies of accelerator physics, THz sources, as well as single-shot Time-Domain spectroscopy will also be discussed.
