Embodiment Construction
[0025] Embodiments of the present invention provide a method for accurately adjusting and stabilizing the repetition frequency of a mode-locked fiber laser, please refer to figure 1 , including the following steps:
[0026] S1: The first step: build and start a mode-locked fiber laser, the resonator of the mode-locked fiber laser has an optical fiber;
[0027] S2: second step: detecting the repetition frequency of the laser pulse output by the mode-locked fiber laser, and judging whether the difference between the detected repetition frequency and the target repetition frequency is within the first preset threshold range;
[0028] S3: The third step: if the difference between the detected repetition frequency and the target repetition frequency exceeds the first preset threshold range, the optical fiber is subjected to shearing and fusion processing. The shearing and fusion processing includes: cutting off part of the optical fiber and then fusion splicing and shearing end, o...
