Abstract: Laser driven plasma accelerators are offering high gradient (∼10-100 GV/m), high quality (low emittance, short bunch length) electron beams, which can be suitable for future compact, bright and tunable light sources. In the framework of the Laboratory for Laser-and beam-drivenplasma Acceleration (LAOLA) collaboration at Deutsches Elektronen-Synchrotron (DESY) the external injection experiment for injecting electron bunches from a conventional RF accelerator into the linear plasma wave is in progress. External injection experiments at REGAE (Relativistic Elec-tron gun for Atomic Exploration) require sub-20fs precision synchronization of laser and electron beams in order to perform a beam scan into the plasma wave by varying the delay between electron beam and laser pulses. In this paper we present a novel optical to microwave synchronizationscheme, based on a balanced single output integrated Mach-Zehnder Modulator (MZM). The scheme offers a highly sensitive phase detector between a pulsed 800 nm Ti:Sa. laser and a 3 GHz microwave reference source. It is virtually independent of input laser power fluctuations and it offers femtosecond long-term precision. Together with the principal of operation of this setup, we will present promising preliminary experimental measurements of the new detector stability.
