| Research Abstract |
A timing distribution system with femto-second stability has been developed for the RF synchronization of accelerator and the laser synchronization of the pump-probe experiments. The system uses a phase stabilized optical fiber(PSOF) and an active fiber length stabilization. The PSOF has 5ps/km/degeeC of the temperature coefficient. The active fiber length stabilization uses the phase detection of the round-trip sinusoidal wave and the deviation is compensated with the fiber stretcher. The time delay stability reached to 20fs in the case of a 900m long PSOF.
