Fiber laser machine enables high-quality laser glass processing

A 1 µm picosecond fiber laser offers improvements in laser glass processing.

Advalue

A laser glass processing machine from AdValue Photonics (Tucson, AZ) drills, cuts, marks, and mills glass materials including soda lime, borosilicate, optical glasses, fused quartz, and coated glasses, providing superior flexibility, quality, and throughput for glass fabrication. With proprietary fiber laser and system design, this machine can drill glass substrates with thickness from 50 µm to 10 mm with hole sizes from 50 µm to 90 mm in diameter. The technology offers little-to-zero taper and micro-crack holes with programmable drilling design. The equivalent drilling speed surpasses conventional mechanical drilling method. For example, it takes only 1.5 s to drill a Ф10 mm hole on 1-mm-thick glass and 3 s on 2-mm-thick glass.

This technology offers a “green” fabrication process: No cooling water is needed as with conventional mechanical processing or waterjet cutting. The machine is equipped with a cutting-edge fiber laser, motion system, camera alignment system, and granite surface plate to provide low maintenance cost, high precision, and boosted productivity.
