Embodiment Construction
[0027] The specific embodiments of the present invention will be described in detail below with reference to the technical solutions and the accompanying drawings.
[0028] A single-cavity double-optical frequency comb generating device with adjustable repetition frequency comprises an optical resonant cavity 1 and an optical frequency comb repetition-frequency regulation module. The optical resonator 1 may be an optical resonator based on technologies such as active mode locking or passive mode locking and capable of generating an optical frequency comb with a specific repetition frequency, for generating a first optical frequency comb with a fixed repetition frequency. The optical resonant cavity 1 includes an optical isolator 2 and a first optical coupler 3 . The optical isolator 2 is used to limit the unidirectional transmission of the optical pulse signal in the entire system to prevent the self-radiation noise light of reverse amplification from being transmitted in the ...
