Example Embodiment
[0063] Example 1
[0064] Please refer to figure 1 and figure 2 As shown, a fiber laser is provided in this embodiment, and seven cylindrical light guide columns 4 are closely arranged in a circle, that is, one light guide column 4 in the middle, and the other six light guide columns 4 closely surround the middle light guide column 4 in the circumferential direction. Arranged, the pigtails of the seven light guide columns 4 can be connected to different fiber laser modules 1, or some of the light guide columns 4 pigtails can be connected to a certain fiber laser module 1, and the laser power of each fiber laser module 1 can be separately The control can also control several or all of them synchronously, so as to realize the change or control of the output light spot characteristics.
[0065] For example, the output laser power of the middle light guide column 4 can be individually controlled, and at the same time, the output laser power of the six light guide columns 4 in t...
Example Embodiment
[0066] Embodiment 2
[0067] refer to image 3 and Figure 4 As shown, another fiber laser is provided in this embodiment, which includes three fiber laser modules 1, wherein two fiber laser modules 1 are each connected to a secondary light guide column, and the other fiber laser module 1 is connected to the main light column. In the fiber laser of this embodiment, auxiliary light guide columns are added around or beside the main light column, which can reduce spatter and homogenize the molten pool, so the output beam of the fiber laser can effectively improve the welding effect.
Example Embodiment
[0068] Embodiment 3
[0069] refer to Figure 5 As shown, another fiber laser provided in this embodiment includes seven fiber laser modules 1 , and each fiber laser module 1 is connected to a light guide column 4 respectively.
