Abstract: A laser beam shaping device includes a multi-zone structure lens and a focusing lens. The multi-zone structure lens includes a lens body and a refractive structure. The lens body has an incident plane and an emission plane, and one of the incident plane and the emission plane is furnished with the refractive structure. The light source passing through the refractive structure deviates and leaves the lens body via the emission plane. The light source passing through the lens body is divided into N sets of light beams. After the N sets of light beams penetrate through the focusing lens, N set of incident beams are formed to project the interface of the first material and the second material in an oblique inward manner with respect to the optical axis of the focusing lens. In additional, a laser processing system and a laser interlocking welding structure respectively are also provided.

Abstract: A light emission module includes a laser source, a beam steering element and a scanning-angle expanding lens set. The laser source is used for emitting a laser beam. The beam steering element is used for receiving the laser beam and splitting the laser beam into at least two laser beams. The scanning-angle expanding lens set, adjacent to the beam steering element, is configured to receive and integrate the at least two laser beams, and to control a spanning angle and a scanning angle between the at least two laser beams on a scanned object. The spanning angle is a visual angle of a vertical scan direction of the scanned object, and the scanning angle is another visual angle of a horizontal scan direction of the scanned object. In addition, a light emission module and a light scanning method are also provided.

Abstract: An apparatus for cutting a multilayer material includes a splitter module and a uniaxial crystal element. The splitter module, located in a transmission path of an incident light beam, is used for splitting the incident light beam into a first polarized light beam and a second polarized light beam. The uniaxial crystal element is disposed adjacent to the splitter module and on a transmission path of the first polarized light beam and the second polarized light beam. The first polarized light beam and the second polarized light beam pass through the uniaxial crystal element individually by having the first polarized light beam and the second polarized light in correspondence to different index of refractions, so that two focuses with different focal lengths can be obtained. In addition, a method for cutting a multilayer material method is also provided.
