Abstract
A compact, background-free, balanced cross-correlator enables (a) the detection of a timing error between two ultrashort pulses with (sub-)femtosecond resolution and (b) the timing synchronization of ultrashort pulse lasers using the output signal of the detector to close a phase-locked loop and can therefore serve as an integral part of femtosecond timing distribution and synchronization systems.
