According to the frequency multiplication mode-locked laser, a repetition frequency can be adjusted in a manner that the free spectrum range of the micro-ring resonant cavity is used as a step length, thereby improving application flexibility and robustness of an existing mode-locked laser based on four-wave frequency mixing efficiency dissipation. The frequency multiplication mode-locked laser has wide application prospect at aspects such as ultrahigh-speed optical communication system, microwave photonics and optical analog-to-digital conversion in future. Particularly, the frequency multiplication mode-locked laser has particularly important application in the fields such as optical information processing and on-chip optical interconnection in which frequency multiplication optical clock signals are required.
