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.

A method of embedding a screen in a substrate includes placing the screen on the substrate, and then melting part of the substrate, so that the screen becomes embedded in the substrate. The melting may involve heating at least part of the screen to melt part of the substrate, or directly heating the part of the substrate. The screen may be a screen of electrically-conductive material, and the heating may be Joule heating in which an electrical current is passed through the screen to heat the screen. Alternatively, the heating may involve microwave, conductive, or laser heating. The produced device of the substrate with an embedded screen may be an optical window with an embedded electromagnetic interference (EMI) screen, may be a touch screen or touch display, or may be a window with an embedded heating element, to give a few non-limiting examples.
