Description

Technical Field

[0001] This utility model relates to the field of laser equipment, specifically to a double-layer fiber disk structure for pulsed fiber lasers. Background Technology

[0002] A laser is a device that generates laser light. Its core principle is based on the energy excitation of atoms or molecules. External energy excitation causes atoms or molecules to transition to an excited state, and then release photons through stimulated emission, forming a coherent beam of light. Fiber lasers use doped optical fibers as the excitation medium and are excited by a pump source to generate high-power continuous laser light, which is suitable for long-distance communication.

[0003] During the use of fiber lasers, the optical fiber is very susceptible to damage from external forces. To solve this problem, fiber optic reels have been developed. By coiling the optical fiber on the reel, it can be protected from damage when the fiber is moved or subjected to external forces. Existing fiber optic reels coil the pigtail and fiber in the same reel at the same time. This method of coiling is prone to errors, resulting in the fiber and pigtail becoming tangled, which increases the difficulty of maintenance for operators. Therefore, a new type of fiber optic reel structure is needed to solve this problem. Utility Model Content
