To address few-shot pulse contrast measurement, we present a correlator coupling the high gain of an optical parametric amplification scheme with large pulse tilt. This combination enables a low sensitivity charge coupled device (CCD) to observe features in the pulse intensity within a 50 ps single-shot window with inter-window dynamic range > 10{sup 7} and < 0.5 mJ input energy. Partitioning of the single window with optical densities to boost the CCD dynamic range is considered.
