摘要： The invention is a method and an apparatus for marking an article and the article thus marked. It includes providing the article. Generating a plurality of groups of laser pulses. At least one of the plurality of groups is generated by modulating a beam of laser pulses to form a plurality of beamlets. Each, of the plurality of beamlets, include at least one laser pulse. It also includes directing the plurality of groups of laser pulses onto the article such that laser pulses within the at least one of the plurality of groups impinge upon the article at spot areas that do not overlap one another, wherein laser pulses within the plurality of groups are configured to produce a visible mark on the article.

摘要： Systems and methods for laser processing continuously moving sheet material include one or more laser processing heads configured to illuminate the moving sheet material with one or more laser beams. The sheet material may include, for example, an optical film continuously moving from a first roller to a second roller during a laser process. In one embodiment, a vacuum chuck is configured to removably affix a first portion of the moving sheet material thereto. The vacuum chuck controls a velocity of the moving sheet material as the first portion is processed by the one or more laser beams. In one embodiment, a conveyor includes a plurality of vacuum chucks configured to successively affix to different portions of the sheet material during laser processing.
