Our third-order autocorrelator measures laser pulse contrast with the highest commercially available dynamic range of up to 12 orders of magnitude. This extreme level of sensitivity allows to identify even lowest background signals and trace tiniest pre- and post-pulse replica for high-field experiments and plasma physics. Its sequential scheme with all-reflective optics ensures measurements without the typical ghost-pulse artefacts. The Tundra reaches its spectacular sensitivity already at 50-150 μJ input energy, making it possible for complex laser systems to search the sources of background contamination already in low-energy stages. The autocorrelator is available for 800 nm and 1030 nm, for a huge range of pulse durations from <20 fs to several picoseconds. With its unique delay range of up to 4 ns the Tundra can find even strongly displaced pre-pulses rising in laser amplification stages from components like Pockels cells or the like.
