  • METHOD AND DEVICE FOR LOCKING REPETITION RATE OF OPTICAL FREQUENCY COMBS
    Publication number: 20240014625
    Abstract: A method for locking repetition rate of an optical frequency comb is provided. A cavity length adjusting actuator is adopted to lock the repetition rate of the optical frequency comb. When a locking state of the cavity length adjusting actuator is in a critical threshold state, an optical delay line of an optical frequency comb optical system is adjusted to adjust the repetition rate of the optical frequency comb, so as to keep locking the repetition rate of the optical frequency comb. A locking device of the repetition rate is also provided, in which an optical delay line control system can judge the locking state of a cavity length adjusting actuator control system in real time, such that the repetition rate can be slowly adjusted within a wide range, and the locking state of the optical frequency comb can be maintained.
