Description
Single-shot ultrafast diagnostics at high repetition rate present
challenging problems, due to the speed limitation of data acquisition
setups. This concerns in particular the cameras which are typically
required in electro-optic sampling and transient reflectivity
setups. Here we explore an alternate way based on the so-called
photonic time-stretch strategy, and which consists in "slowing-down"
the signals by optical means before recording. We present a set of
results using this strategy in the case of electro-optic sampling of
THz pulses at SOLEIL [1], and electro-optic sampling of the electron
bunch near-field at ANKA [2,3]. In particular we show how this type of
experiment can provide a direct observation (turn-by-turn) of electron
bunch structures created by the microbunching instability in storage
rings.
