A method for producing a cavity in a substrate composed of hard brittle material is provided. A laser beam of an ultrashort pulse laser is directed a side surface of the substrate and is concentrated by a focusing optical unit to form an elongated focus in the substrate. Incident energy of the laser beam produces a filament-shaped flaw in a volume of the substrate. The filament-shaped flaw extends into the volume to a predetermined depth and does not pass through the substrate. To produce the filament-shaped flaw, the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses. After at least two filament-shaped flaws are introduced, the substrate is exposed to an etching medium which removes material of the substrate and widens the at least two filament-shaped flaws to form filaments. At least two filaments are connected to form a cavity.

The invention relates to a method for manufacturing a hollow glass article including a step of marking the hollow glass article thus formed by laser, the surface of the hollow glass article being at a temperature between 400° C. and 600° C. The marking step consists in making filiform decorations by producing at least one continuous and shiny groove on the surface of the hollow glass article.

The laser grooving step includes a step of irradiating a first laser beam having a first pulse width, to remove the wiring layer in an edge portion of the dicing region, and a step of irradiating a second laser beam having a second pulse width which is longer than the first pulse width, to remove the wiring layer inside from the edge portion.

A cutting method for a display panel, wherein the cutting method includes: cutting a display motherboard to be cut into a plurality of separate display panels by using a first laser beam, wherein the display panels each include a plurality of leads disposed between conductive connectors and a cutting edge of the display panel formed after cutting by the first laser beam; and severing at least some leads of the display panel by using a second laser beam at a position on the display panel between the conductive connectors and the cutting edge of the display panel, the at least some leads being short-circuited leads.

A tool allows a user to create new designs for apparel and preview these designs in three dimensions before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. Based on a laser input file with a pattern, a laser will burn the pattern onto apparel. With the tool, the user will be able to create, make changes, and view images of a design, in real time, before burning by a laser. The tool can be accessed or executes via a Web browser.
