The RRE-SYNCRO features a dual channel PID controller, an integrated phase detector and integrated amplifier modules for the stabilization of the laser cavity, aswell as integrated photo diode modules for laser repeition rate detection at fundamental and harmonic frequencies.
The modular design allows versatile adaptation of the system to all Menlo lasers,
and also to a wide range of lasers from other manufacturers.
