Abstract
Optical phase locking of a diode laser to a mode of a femtosecond optical comb has been achieved with a system that joins the advantages of analog and digital phase detectors. Low noise and fast response are combined with broad phase range and lock reliability. Details of the circuit are illustrated, and properties of the different phase detectors in view of optical frequency measurements are discussed.
