 note = {The temporal contrast of an ultrahigh-intensity laser is a crucial parameter for laser plasma experiments. We have developed a multichannel crosscorrelator (MCCC) for single-shot measurements of the temporal contrast in a high-power laser system. The MCCC is based on third-order crosscorrelation, and has four channels and independent optical delay lines. We have experimentally demonstrated that the MCCC system achieves a high dynamic range of >10^12 and a large temporal window of >1 ns. Moreover, we were able to measure the shot-to-shot fluctuations of a short prepulse intensity at -26 ps and long-pulse (amplified spontaneous emission, ASE) intensities at -30, -450, and -950 ps before the arrival of the main pulse at the interaction point.},
