Cold Laser Cutting for Glass Substrates
Principle of Cold Ablation: Overcoming Traditional Limitations
Cold laser cutting utilizes ultrafast picosecond pulses to process glass substrates through non-thermal ablation, avoiding the micro-cracks and chipping typical of CO₂ lasers. By maintaining pulse durations below 10 picoseconds, Lecheng’s systems achieve peak power densities that vaporize materials directly without heat transfer to surrounding areas. This technology enables fragment-free cutting of ultra-thin glass (0.1–2mm) while increasing edge strength by 300% through proprietary thermal stress control—critical for foldable displays and photovoltaic substrates.
Precision Applications in Solar and Display Industries
In perovskite solar manufacturing, cold laser cutting creates clean edges with ≤20μm accuracy for monolithic module integration, minimizing dead zones. Lecheng’s systems process laminated/tempered glass effortlessly, achieving <30μm edge chipping for automotive screens and photovoltaic substrates. The non-contact process eliminates contamination risks while supporting complex shapes through CAD integration, making it ideal for high-value applications requiring micron-level precision.
Industrial Scalability and Quality Assurance
Lecheng's picosecond laser cutting systems maintain 24/7 operational reliability with minimal maintenance, featuring automatic focus control and real-time quality monitoring. The equipment achieves >99.8% yield in mass production environments, with integrated cleavage mechanisms enabling ≤10μm precision for high-alumina glass up to 10mm thickness. These systems demonstrate exceptional adaptability across solar, automotive, and consumer electronics sectors.
Cold laser cutting represents a paradigm shift in glass processing, combining sub-micron precision with industrial robustness. Lecheng’s technology not only enables new applications in flexible electronics and high-efficiency solar cells but also sets new standards for manufacturing quality and operational efficiency.
