…the characteristics of the glass itself, to develop more advanced coatings, and also to improve the process for cutting glass, in terms of higher precision, greater speed, reduced environmental impact, and lower cost. This article provides an overview of laser glass cutting technology, and explores…

…Figure 3. A CO laser with only 9W of output power produced this clean, curved cut (6 mm radius circle) in thin glass (50 µm thick) at a feed rate of 140 mm /sec. Laser Ablation Laser ablation relies on a completely different mechanism to process glass than CO2 and CO lasers, which utilize thermal…

…SmartCleave Filamentation Cutting Glass cutting can also be accomplished through a specific form of internal modification, called filamentation, which again utilizes the very high power densities achieved with focused, ultrafast lasers. In this case, the high laser intensity produces self-focusing…

…ultrafast lasers for bottom-up drilling or cutting. In addition to limited cutting speed and some edge roughness, the other limitation of topside scribing using an ultrafast laser is a taper always remains on the scribe or hole, usually in the 8° to 12° range. Within ultrafast lasers, cut quality…

Many traditional applications rely on infrared and visible Qswitched lasers, which have pulse widths in the tens of nanoseconds range, and which remove material via a photothermal interaction. Here, the focused laser beam For Glass and Silicon Wafer Cutting, Shorter…

…no cracks, and zero residual stress in the glass. The result is a better quality cut, stronger glass, and a wider cut process window. The CO laser also enables radial (freeform) glass cutting; in contrast, CO2 lasers can only produce straight line cuts because the inherently round output beam must…
