Temporal slicing of intense multi-THz transients using an ultrafast semiconductor switch

Here, we present a scheme that employs an ultrafast plasma mirror (UPM) to slice intense multi-THz transients from our high-field THz laser source with a sub-cycle precision. For the first time, to the best of our knowledge, the fastest temporal slicing of multi-THz transients is observed using a field-resolved electro-optic detection scheme.
