Glass is a non-crystalline, brittle, inorganic and predominantly silicate-oxide material whose properties are influenced by the type and quantity of oxides. Laser marking and laser engraving of glass separates the wheat from the chaff. The challenge when marking or engraving on glass is that this material is usually transparent to the typical wavelengths of industrial lasers. Therefore, in addition to the correct laser wavelength, the method and process must also be developed.
Typical applications for laser marking and laser engraving on glass include the industrial marking of drinking glasses. ACI Laser has taken up this challenge and developed several solutions for engraving and marking glass.
