A new way to permanently apply metal onto glass by laser ablation was developed at Laser Mark’s Company. Previous through glass ablation efforts did not provide high adhesion and could be easily rubbed off. The Laser Mark’s Company process combines a specific MOPA pulse width to simultaneously couple with the glass surface when vaporizing a sacrificial adjacent metal shim. The vaporized metal fully adheres to the glass that is selectively heated. No stress to the glass is applied and the process works with Brass, Stainless Steel, and even aluminum. Note on the video how the metal can not be removed even by a high pressure erasure. Laser Mark’s Company can do this as a job shop service or design a custom laser system for in-house processing.
