      • Advanced Laser Process

      • 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

      • Laser Cutting Display and Strengthened Glass and Glass Substrates

        Corning Laser Technologies' laser cutting processes employ ultra-short laser pulses in the picosecond range that cut glass, utilizing nonlinear processes. This ensures a low as cut edge roughness, increased cut bend strength, and a higher throughput. Corning’s laser glass cutting thus enables superb as cut quality, maximum output and yield in high volume production of touchscreen displays for smart phones, tablet PCs and other consumer products.

        With an as cut edge roughness at < 2µm, in most cases the cut glass can be used for subsequent processing without additional intermediate steps for time and cost consuming post-processing. Glass pieces cut with Corning Laser Technologies' unique laser glass cutting process have superior break strength behavior, compared to items cut by other laser methods and conventional mechanical glass cutting processes.

      • Laser Drilling

      • Laser Drilling Glass

        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.
