The invention of a femtosecond stable Laser-to-RF phase detector allows to measure with femtosecond precision the relative phase between a phase stable optical reference and an RF signal. Thereby one can stabilize RF reference signals in modern FELs on a femtosecond scale. A pulsed optical synchronization system is used to deliver the required optical reference signals. The L2RF phase detector is based on an integrated Mach-Zehnder modulator (MZM) in which the phase error between both signals is encoded in an amplitude modulation of the optical pulse train. Different configurations for different operation scenarios have been evaluated. A full mathematical representation has been derived. The impact of multiple error sources has been investigated. Error sources of the measurement setup have been identified and eliminated. The femtosecond performance has been verified with two different prototypes. The achieved stability of 3.6fs over 12h is currently unmatched.
