As with regular etched mirrors, the initial focus of laser engraving machines was to etch an image onto the glass surface of the [[mirror]]. When power, focus and speed are optimized, similar results to [[sandblasting]] or [[Chemical milling|chemical etching]] can be achieved.

In a new form of mirror engraving<ref>{{Cite web |date=2024-07-16 |title=Expert Guide For You To Laser Engrave Glass |url=https://craftetch.com/laser-engrave-glass/ |access-date=2024-07-29 |language=en-US}}</ref> the laser pulsates through the reflective silver layer at the rear of the mirror. As a result, the glass side of a laser engraved mirror remains intact, maintaining the full reflective qualities of the original mirror.

After the engraving process in finished, the rear of the mirror needs to be "filled" with a new coating to bring out the lasered detail. When a photograph or text is laser engraved, a rear coating of solid black will lend monochromatic images the greatest definition. Coloured coatings can supply chromaticity.
