How does laser engraving work? Today the glass engraving

Laser engraving on glass with a UV laser works by using targeted laser energy to heat and melt the glass in a specific area, permanently marking it.

A UV laser operates at a higher frequency than a traditional CO2 laser and emits light in the ultraviolet range. When this laser is aimed at the glass, the energy of the light is absorbed by the glass surface, causing the glass to be locally heated and melted.

The laser is typically controlled by a computer, which inputs into the laser the pattern or design to be engraved into the glass. The laser then moves precisely over the glass surface and burns the pattern into the glass.

The engraving depth depends on the laser energy, burning time and other parameters that can be adjusted by the operator. Deeper engraving requires more laser energy and longer burn time, resulting in more material removal.

UV laser engraving on glass offers advantages such as high precision, fast processing speed and the ability to engrave fine details. The marked designs can be very durable and are resistant to abrasion and wear.
