…residual stress than CO2 cutting, yielding a stronger cut piece, together with a wider process window for the manufacturer. The other exciting aspect of CO lasers in glass cutting is their ability to support the cutting of curves. CO2 lasers are typically limited to cutting glass in straight lines…

cutting leaves significant mechanical stress in the finished edge. (In fact, it becomes difficult to use mechanical cutting at all with substrates below about 1 mm in thickness because the glass is so easily broken). To prevent further cracking or breaking of the glass after the original cut, it may…

…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 using a femtosecond…
