Abstract

The invention discloses a fiber laser and a laser material processing system. The fiber laser includes a laser output head and a plurality of fiber laser modules, the laser output head includes a plurality of light guiding columns which are arranged in parallel in space, each light guiding column corresponds to a transmission fiber and is connected to one of the multiple fiber laser modules through the transmission fiber, and by controlling or distributing the output power of different fiber laser modules, the profile characteristics of output beams of the light guiding columns are adjusted orchanged. According to the fiber laser and the laser material processing system, through spatial arrangement of the multiple light guiding columns, the light guiding columns are connected with one ormore fiber laser modules, and the profile characteristics of the output beams are changed; and by changing the output power of the corresponding fiber laser modules, required output light spot distribution can be obtained, continuous and real-time adjustment of output light spots can be achieved, the implementation scheme is flexible and diverse, the manufacturing process is relatively simple, andthe manufacturing cost can be effectively lowered.

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 the circumferential direction can be controlled uniformly. The output light spot can be changed into a Gaussian energy distribution, a ring-shaped spot distribution, or a quasi-flat-top energy spot distribution; if necessary, each light guide column 4 can also be connected to fiber laser modules with different wavelengths 1, or form multiple combinations, that is, some of the light guide columns 4 are connected to a certain fiber laser module 1 of the same wavelength, so as to realize some special applications.

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.
