Title:
FIBER-COUPLED LASER SYSTEM CAPABLE OF CONTROLLING BEAM SHAPE, WELDING DEVICE, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/238942
Kind Code:
A1
Abstract:
Provided is a laser system comprising a plurality of laser light sources and a plurality of collimating lenses. The system is further provided with a collection lens configured to receive a laser beam output from the plurality of collimating lenses, and to collect the laser beam at one or more collection points in a core region or an outer cladding region of an optical fiber. The optical fiber includes a core region, an inner cladding region, and an outer cladding region. The optical fiber is configured to output a dual laser beam comprising a main beam which is generated in the core region, and a ring beam which is generated in the outer cladding region so as to surround the main beam. The plurality of collimating lenses are each individually disposed in a respective position so as to adjust the position of the collection point in one of the core region and the outer cladding region of the optical fiber.
