Synergetic Repetition Frequency Locking of an Optical Frequency Comb

Abstract

Abstract This paper proposes a method to achieve long-term locking of the repetition frequency of the optical frequency comb under severe temperature fluctuations by cooperatively adjusting the cavity length of the resonator using piezoelectric ceramic, temperature control module, and delay line module. This method enhances the practicability and usability of optical frequency comb at a low cost.
