Abstract
A method and system for stabilizing the phase relationship of two RF-controlled mode locked lasers involves monitoring the output of both lasers and, with a phase detector/comparator, generating a voltage proportional to the phase difference between the two lasers. The voltage is amplified and filtered and fed into a voltage controlled phase delay connected to the mode locker of one of the lasers. The phase delay operates to delay the RF signal to the one laser according to the desired phase relationship. By disclosed methods and apparatus a single laser can also be stabilized to its own RF drive source to reduce noise effects, two lasers can be individually stabilized to a single RF source, or two lasers can each be stabilized to their own separate RF sources.
