The TUNDRA® third-order autocorrelator is a highly sensitive diagnostic tool for laser pulse contrast measurements. After further development, the dynamic range reaches up to 14 orders of magnitude — sufficient to characterize the background and detect even the tiniest pre- and post-pulse replicas of the most powerful lasers in the world.

The autocorrelator employs all-reflective components, guaranteeing correlation traces free of measurement artefacts. In contrast to second-order autocorrelators, pre- and post-pulses can be distinguished due to the third-harmonic nature of the signal. These features make our specialized fully-automated autocorrelator an invaluable tool for state-of-the-art contrast characterization of ultrashort and intense laser pulses.

TUNDRA has been used to characterize some of the most powerful and unique terawatt- and petawatt-class laser systems in the world, including ATLAS (Garching, 50-250 TW), PFS (MPQ, 100 TW), SYLOS (ELI-ALPS), APOLLON (Palaiseau, up to 5 PW), PHELIX (GSI, 500 TW), and SALLE JAUNE (LOA, 200 TW).

Key Product Features
