…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…

…by heating with a CO2 laser. With chemically or thermally strengthened glass, internal stress within the part provides for automatic separation of outer contours, without an additional step. Figure 6. SmartCleave enables high speed cutting of curves and insets into glass, e.g. used for substrates…

…scribe, cut or mark a material. 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…
