A method of assembling together a first part and at least one second part that are made of materials compatible with bonding by molecular adhesion includes a step of pressing a first surface of the first part against a second surface of the second part so as to create molecular bonds at an interface between the parts, and a step of consolidating the interface bonding as created in this way by heat treatment. The consolidation includes a step of emitting a power laser beam towards an impact point forming a portion of the outline of the interface, and a step of moving the impact point along the outline of the interface.

A method of manufacturing a cell unit substrate, includes: a modified zone-formation step in which modified zones are formed along a predetermined cutting line on the mother substrate to be spaced apart from each other by a first distance by irradiating the mother substrate with laser beams having an energy intensity within an ablation threshold of the mother substrate along the cutting line, a modified zone-etching step in which through-holes are formed along the cutting line on the mother substrate to be spaced apart from each other by the first distance by etching the modified zones, a surface strengthening step in which the mother substrate having the through-holes therein is subjected to surface strengthening, with the mother substrate dipped in a strengthening solution, and a substrate separation step in which the cell unit substrates are separated from the surface-strengthened mother substrate.

A method for hardening a transparent material includes the steps of introducing a material modification to the transparent material using a laser beam of ultrashort laser pulses of an ultrashort pulse laser so as to harden at least a portion of the transparent material.

Methods, apparatus, and systems for mitigating pinhole defects in optical devices such as electrochromic windows. One method mitigates a pinhole defect in an electrochromic device by identifying the site of the pinhole defect and obscuring the pinhole to make it less visually discernible. In some cases, the pinhole defect may be the result of mitigating a short-related defect

A label is attached to a base material in a container. The container includes patterns formed in a plurality of stages on the base material by laser irradiation. The patterns may include an aggregation of dots formed by the laser irradiation. The container may further include a first information region and a second information region. Information including a numeral, a symbol, or an image is made visible by the patterns in the first information region. The second information region is formed on the label. Information including a numeral, a symbol, or an image is made visible in the second information region.

The present invention relates to a method for marking a container comprising at least a transparent wall comprising the following steps: a) applying at least one spot of ink on an outer surface of said transparent wall, b) heating said transparent wall, c) engraving a data matrix in the spot of ink of said transparent wall. The invention also relates to a marked container and to a method for identifying such a marked container.

Information is stored in an optical element in the form of a glass or plastic body embodied as spectacles lens, spectacles lens blank or spectacles lens semi-finished product. The information in the form of data is stored on or in the glass or plastic body by creating at least one marking with a marking system. The marking can be read by a reading apparatus. The marking system has an interface for reading information individualizing the optical element. The marking is created permanently by the marking system on or in the optical element at a definition point of a local body-specific coordinate system set by two points on or in the optical element. In this body coordinate system, the manufacturer specifies the position of the lens horizontal and/or the far and/or the near and/or the prism reference point.

An apparatus includes a fiber feeding system to deposit a fiber on an edge of the glass article and a laser system. The laser system is positioned to project a first and a second laser beam onto a first and a second side of the fiber, respectively. The laser system is positioned to project a third laser beam onto the edge of the glass article. A method includes advancing a glass article relative to a fiber; positioning the fiber in relation to an edge of the glass article, contacting a first side of the fiber with a first laser beam, contacting a second side of the fiber with a second laser beam, depositing the fiber on the edge of the glass article, and contacting the edge of the glass article with a third laser beam.
