Marking of glass with fiber laser marking machine
Laser polishing of copper metal for contrast is a relatively well-known method, but because of the inherent high reflectivity of this metal, it is often more difficult to obtain dark marks. The Silicon Valley Technology Center (SVTC), a subsidiary of IPG Photonics, has developed this type of technology to produce a dark surface with an L* value of <30 on the surface of copper materials.
Unexpectedly, almost the same parameters as those used for copper materials can also be applied to marking the upper and lower surfaces of uncoated borosilicate glass. This further supports the hypothesis that nonlinear absorption is due to the influence of high peak power fiber lasers. Checking the scribing area, you can see that the "cracking" is very limited, with cracks <10μm and surface roughness <5μmRa.
As a manufacturer of small and medium power laser equipment, Jiaxin Laser has always been researching various laser equipment that meets market needs, large-format fabric laser cutting beds, hand-held marking machines, and of course this economical small laser marking machine .
