We propose a novel single-shot pulse-contrast measurement approach based on high-order quasi-phase-matching (QPM) cross correlation. It supports perfect contrast measurement with features of no artifacts, high resolution, and large temporal window. The prototype experiment based on the noncollinear third QPM with a beam crossing angle of 90 deg, using femtosecond Ti:sapphire laser pulses with a contrast of 107, demonstrates an artifacts-free measurement with a temporal window of 70ps and a resolution of 900fs.
