Corning also offers in-house process development and tailored solutions for full automation – leveraging more than 20 years of experience in precision laser machining, along with more than 150 years of material science expertise, for a one-stop-shop for laser processing requirements.
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.

Corning Laser Technologies' laser drilling works for both unstrengthened and strengthened glass, as well as other brittle materials.
Our drilling processes employ ultra-short laser pulses (in the picosecond range) that remove glass through nonlinear effects. The technology can be used to drill glass with extremely low wall taper and little to no micro cracks. Beyond drilling, any geometry can be cut, including cut-outs such as circles or slots, closed-form and radius form factors.
Drilling of Brittle Materials
Corning Laser Technologies' laser drilling works for both unstrengthened and strengthened glass, as well as other brittle materials. The process is clean room compatible, because it generates close to zero material loss and debris.

CLT has further developed the nanoPerforation process to enable the cutting of 3D shaped glass. Thanks to the high edge quality of the nanoPerforation process, there is little or no post-processing required. As laser cutting is contactless, it does not need process fluids and there is no tool wear. These attributes help reduce the total cost of ownership and make the CLT nanoPerforation not only more flexible, but also more cost effective than traditional MS&B processes.
