A method for automatically locking frequency of an optical frequency comb is performed through locking the microwave repetition frequency signal and the microwave carrier-envelop offset frequency signal of the optical frequency comb. The microwave repetition frequency signal is subjected to filtering, frequency division, and phase discrimination with a first reference signal to obtain a first error signal. A first output frequency of the frequency synthesizer is adjusted based on a direction of the first error signal and a first voltage signal. The microwave offset frequency signal is subjected to filtering, frequency division, and phase discrimination with a second reference signal to obtain a second error signal. A second output frequency of the frequency synthesizer is adjusted based on a direction of the second error signal and a second voltage signal.
