Description

A compact, longitudinal diagnostics for fs-scale electron bunches using a THz
electric-field transient in a split-ring resonator (SRR) for streaking will be
tested at the Ferninfrarot Linac- Und Test- Experiment (FLUTE). For this new
streaking technique, intensive THz pulses are required, which will be
generated by laser-based optical rectification. We present a setup for
generating THz pulses using tilted-pulse-front pumping in lithium niobate at
room temperature. Excited by an 800 nm Ti:Sa pump laser with 35 fs
bandwidth-limited pulse length, conversion efficiencies up to 0.027% were
achieved. Furthermore, the status of the SRR experiment is shown.
