A drift free synchronization distribution system with femtosecond accuracy is of great interest for free-electronlasers such as FLASH or the European XFEL. Stability at that level can be reached by distributing laser pulses from a mode-locked erbium-doped fiber laser over lengthstabilized fiber-links. In this paper, we present a prototype of a fiber-link stabilization system based on balanced optical cross-correlation. The optical cross-correlation offers drift-free timing jitter detection.doi:10.1109/pac.2007.4439912 fatcat:olbesysoozhxvn45oc6tvponte
