The invention relates to a laser processing system which comprises a laser power combiner, one or a plurality of laser modules, a laser coupler and a laser transmission system. A plurality of input optical fibers are arranged at one end of the laser power combiner, and a multi-clad output optical fiber is arranged at the other end of the laser power combiner. The laser transmission system is made of a multi-clad optical fiber. The one or the plurality of laser modules are respectively connected with the laser coupler through one input optical fiber of the laser coupler, the laser coupler is respectively in end connection with the plurality of input optical fibers of the laser power combiner through a plurality of output optical fibers of the laser coupler, and the multi-clad output optical fiber of the laser power combiner and the laser transmission system are connected onto an output part. The laser processing system can have lasers with different light beam qualities so that the same laser system can simultaneously have various processing functions, flexibility of the laser processing system is greatly improved, and system cost is reduced.
Description
technical field [0001] The invention belongs to the field of laser processing systems, in particular to a laser processing system based on a multi-clad optical fiber power combiner and a transmission system. Background technique [0002] Fiber laser has the advantages of excellent beam quality, high conversion efficiency, full optical path structure, and convenient maintenance. It is currently widely used in many industrial fields, such as: material cutting, drilling, welding, marking, cladding, etc. For different materials, different industrial applications, and different processing techniques, different beam qualities and modes are usually required. Typically Q-switched pulsed lasers are often used to achieve standard, high beam quality (M 2 <2) Medium and high-power continuous lasers are often used for precision processing such as cutting and drilling, while welding, cladding and other processing often require multi-mode beams to complete. In the past, different proc...
