How does the laser photo crystal engraving process work?
Inside our laser crystal engraving machines, high intensity laser beam is focused into a transparent crystal. At its focal point, the laser beam intensity is high enough to cause a structural change so a point is marked permanently. In the beam path, the light intensity is not enough to cause any changes. By marking and connecting many dots through computer control, a complete image is formed inside a crystal while its surface remains unaltered and smooth. Unlike photo printing, the laser crystal engraving process does not use any chemicals nor produces any wastes. It is truly a green process.
