Laser Engraving Process For Crystal Crafts
- Aug 20, 2018 -

In fact, the most commonly seen crafts are not real crystals, but artificial crystals. "Laser" is the artificial crystal (also known as "Crystal Glass") for the "inner carving" the most useful tool.

The use of laser engraving technology, the plane or three-dimensional pattern "carving" in the crystal glass inside. Carving is an ancient art, the general carving process is carved from outside, from the outside of the material carved the desired shape, and the laser can be like the Monkey King "deep hinterland" to display their hands and feet. Careful examination, these glass, crystal products around completely no for "knife" in and out of the openings, in this regard, laser than the Monkey King is also more brilliant, sun monkeys to others belly when drilling also need to have a gap to do it! The principle of laser engraving is also very simple. Laser to be able to carve glass, its energy density must be greater than the damage to the glass of a critical value, or threshold, and the laser somewhere in the energy density and the size of the spot in the spot, the same beam of laser, the smaller the intensity of the space generated by the greater energy density. Thus, by proper focusing, the energy density of the laser can be lower than the damage threshold of glass before entering the glass and reaching the processing zone, and in the desired processing area is more than this threshold, the laser in a very short period of time to generate pulses, the energy can be in a moment to make the crystal crack, resulting in a tiny white spot, Carve a predetermined shape inside the glass, while the rest of the glass or crystal remains intact.
