For industries like consumer electronics and automotive displays, balancing cutting speed and quality remains a key challenge. Conventional ultrafast laser processing often faces trade-offs: higher speeds may increase edge defects, while lower speeds compromise throughput. Our latest infrared picosecond laser-assisted glass cutting technology addresses this with a breakthrough solution.
By combining a non-diffractive Bessel beam with infrared picosecond laser emission and precise polarization control, the system achieves high-speed, low-defect and high-precision cutting. Linear polarization parallel to the scribing direction optimizes microcrack propagation, enabling large center-to-center spacing (multi-micron range) between modifications—boosting processing efficiency while maintaining edge quality and high precision. Test results show:
Cutting speed up to 80 mm/s for 100μm ultra-thin glass
Edge roughness below 1μm (Ra)
Compatibility with soda-lime, high-index, and flexible glass
Cutting precision less than 0.01mm
This infrared picosecond laser technology excels at complex contour cutting (e.g., rounded corners, curved surfaces) for smartphone cover glass, AR eyewear, and automotive HUD components. It integrates seamlessly with automated production lines, supporting mass production with stable, repeatable quality. The system’s flexible parameter adjustment minimizes tool changes and reduces overall operational costs, making it suitable for both high-volume manufacturing and customized production.
Key Applications:
Smart device cover glass (foldable/non-foldable)
AR/VR high-index optical components
Automotive interior and display glass
