Our third-order autocorrelator serves as a highly sensitive diagnostic tool for laser pulse contrast 

measurements. After further development [1], the dynamic range reaches up to 14 orders of 

magnitude, enough to characterize the background or trace the tiniest pre- and post-pulse replicas 

of the most powerful lasers in the world. The autocorrelator employs all-reflective components 

(apart from signal generating non-linear crystals), guaranteeing correlation traces free of 

measurement artefacts. It can be employed in a wide range of applications. In particular, high 

intensity experiments in plasma physics require in depth understanding of the pulse contrast and 

possible parasitic pulse structures. Contrary 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 automatized autocorrelator an invaluable tool for state-of-the-art contrast 

characterization of ultrashort and intense laser pulses.
