Description

We present a fully automated fiber-optic timing distribution and synchronization system developed for high-power laser facilities that require few-femtosecond synchronization between multiple beamlines, each equipped with an independent seed oscillator.
Building on our previous work in pulsed-optical timing distribution using femtosecond lasers and ultra-low-noise stabilized fiber links*, the system achieves an out-of-loop timing drift of just 5.2 fs RMS over 10 hours between a Ti:Sa laser at 780 nm and a Yb laser at 1030 nm, synchronized remotely via fiber-optic links.
The system includes out-of-loop optical delay lines, integrated into the master platform and a coaxial RF distribution subsystem operating in parallel to the fiber-optic links. This allows high-precision, full pulse-period delay tuning of 13 ns, enabling deterministic phase bucket selection across all synchronized beamlines.
An automatic re-locking mechanism restores pulse alignment across all beamlines after oscillator restart without user intervention. The system integrates natively with EPICS control environments and supports robust 24/7 operation, enabling reproducible, high-precision pump–probe experiments.
