Conventional laser cutting is based on rapid heating processes, leading to vaporization and material removal. This method tends to create micro-cracks, chip-outs and a rough surface finish, which makes time consuming and costly subsequent grinding and polishing steps necessary, leading to low production yields. Using specialty tuned lasers to cut glass by disassociation rather than ablation, the Corning laser glass cutting technology provides numberous benefits: 

Smooth Edges - The 'as-cut` edge roughness may significantly reduce or in some cases even eliminate post-processing and thus process time and cost. 

High Break Strength - The 'as-cut` edge demonstrates superior break strength over other laser and conventional cutting processes as measured by 4 point bend tests.

Multi-Layer Stacks - The system enable cutting of assembled functional multi-layer stacks with and without air gaps, where cutting depths can be adjusted. 

Remarkable Technology
Corning's material science and optic capabilities and unique advantages to the laser glass cutting process. It offers not only distinct advantages over conventional cutting processes, but also over other laser cutting systems. Using ultra-short laser pulses, the material is cut by material disassociation rather than ablation. The result is very low surface, increased as-cut bend strength and faster throughput. The Corning laser process enables cutting strengthened glass, un-strenghthened glass, as well as other transparent glass and crystalline materials.
