Transparent material processing with an ultrashort pulse laser

Methods, devices, and systems for ultrashort pulse laser processing of optically transparent materials are disclosed, with example applications in scribing, marking, welding, and joining. For example, ultrashort laser pulses create scribe features with one pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. Slightly modifying the ultrashort pulse laser processing conditions produces sub-surface marks. When properly arranged, these marks are clearly visible with correctly aligned illumination. Reflective marks may also be formed with control of laser parameters. A transparent material other than glass may be utilized. A method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. In some embodiments of transparent material processing, a multifocus beam generator simultaneously forms multiple beam waists spaced depthwise relative to the transparent material, thereby increasing processing speed.

Image display medium, image-forming method and image-forming apparatus capable of repetitive writing on the image display medium

Provided are an image display medium which satisfies, a safety and a high-speed response and which is capable of repetitive rewriting, an image-forming method in which an image can be formed on the image display medium, and an image-forming apparatus. An image display medium is formed by interposing black particles and white particles between a display substrate and a non-display substrate made of a dielectric. A printing electrode first applies an AC voltage to frictionally charge the black and white particles, and then applies a DC voltage adapted to an image between the substrates. The black particles adhered to a portion (non-image portion) to which the voltage of the display substrate is applied are moved to the non-display substrate.

Imaged article on polymeric substrate

Patterned articles, such as RFID antenna, are made by subablation, a process comprising the steps of:A. providing a substrate having a coating, such as a metal or metal oxide, and an interface comprising the thin region where the coating and the substrate are closest to each other;B. exposing at least one part of the total area of the coating to a flux of electromagnetic energy, such as a focused excimer laser beam, sufficient to disrupt the interface but insufficient to ablate the coating; andC. removing the parts of the coating in registry with the portion of the interface area that was disrupted, by means such as ultrasonic agitation.The process has advantages over photo-resist processes in that there is no residual chemical resist left on the product and no undercutting of the pattern or image. It has advantages over laser ablation processes in that higher throughput is possible at the same energy level and there is no microscopic debris left on the product surface.

Color laser engraving and digital watermarking

A color laser engraving method engraves a document including a surface layer and one or more sub-layers. The sub-layer includes different colors and orientations of ink. A laser provides openings in the surface layer—to expose color ink in the sub-layer—to create color images and / or text. The different orientations of the colored inks include, e.g., circular, linear and overlapped groupings of ink. A sub-layer preferably includes many repeated instances of the grouping. A digital watermark is embedded in a document via transfer of the digital watermark in an embedded image or text, or by pre-embedding the document via altering intensity of colored inks on the original document card stock. A digital watermark can be carried via modulation with a pseudo-random noise sequence.
