laser cut glass can typically withstand two to three times as much force as mechanically cut glass. Figure 1. Comparison of mechanically cut (left) and laser cut (right) glass. The mechanically cut glass shows significant residual stress, and substantial debris from the cutting process. Laser

…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…

…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…

…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…

…stress in the glass, resulting in higher edge strength. In one technique, called laser scribing, the output of a CO2 laser is focused onto the surface of the glass, which is being translated to create a continuous cut. Since all glasses strongly absorb the 10.6 µm, all the laser energy is deposited…

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…
