Ultra-high dynamic third order autocorrelator — •Karl Schmid, Laszlo Veisz, Yutaka Nomura, and Ferenc Krausz — Max-Planck-Inst. of Quantum Optics, Hans-Kopfermann-Str. 1, D-85748 Garching, Germany

The temporal structure of ulrahigh intensity lasers is a major concern in various laser-plasma experiments as ion acceleration or surface harmonic generation. Prepulses or a pedestal (long backgroung pulse) can significantly alter the interaction. The characterization of the contrast of these prepulses/pedestal requires a specially designed autocorrelator capable to measure We prepared a fully automatized, ultrahigh dynamic range (8-10 orders of magnitude), third order autocorrelator. The device is based on cascaded third harmonic generation and can be operated with a small portion of the laser light ( 50 µJ). Application of the correlator for characterization of pulse cleaning will also be presented.
