Embodiment 1
[0045] A method for preparing a micro-nano optical fiber mode-locking device provided in this embodiment includes steps:
[0046] S1, preparing the micro-nano optical fiber segment, including the following specific steps:
[0047] S1-1. Prepare common commercial single-mode optical fiber, use fiber stripping pliers to peel off the coating layer of common commercial single-mode optical fiber located in the middle part, and obtain the optical fiber whose middle part is the bare optical fiber segment, and wipe the fiber with alcohol-soaked fiber wiping paper Wipe off any debris remaining on the bare fiber section.
[0048] In this embodiment, the common commercial single-mode optical fiber used is a commercial Corning optical fiber; the length of the bare optical fiber section is 5-10 mm.
[0049] In this embodiment, before corroding the bare fiber segment on the optical fiber whose middle part is a bare fiber segment, a step is further included: fixing the optical fiber whose mid...
