3D Laser Crystal Eiffel Tower Crystal laser photo 3D laser engraving is a special method, which enables us to form pictures or different types of three dimensional shapes into crystal glasses. This made possible by the improvement of Nd:YAG laser-technology. The laser beam gets through the wall of the glass and at a defined point it changes the structure of the glass by creating microcracks. The picture is being built up by thousands of cracks like that. Now at Jasmine Crystal Ltd. you can also design your own 3D glasses, Your image is converted into 3d laser crystal image and then to be engraved into this3D photo laser crystal.
