A laser glass sculpture of a caffeine molecule. A bubblegram (also known as laser crystal, Subsurface Laser Engraving, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that has been exposed to laser beams to generate three-dimensional designs inside.
5D optical data storage (also branded as Superman memory crystal, [1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process. [2]
A 3D image engraved in a glass cube, seen from various angles. Since 2009, use of SSLE has become more cost effective to produce 3D images in souvenir 'crystal' or promotional items with only a few designers concentrating on designs incorporating large or monolithic sized crystal.
Her website also has crystals that have been laser etched with three-dimensional patterns, including models of nearby stars, the DNA macromolecule, and the Milky Way Galaxy. Grossman's works have featured in art galleries around the world, as well as The New York Times, and the television series Numb3rs and Heroes.
Laser crystal may refer to: Active laser medium, the source of optical gain within a laser; Bubblegram, a 3D image composed of points suspended in a medium, ...
Schematic representation of a cross-section through a 3D optical storage disc (yellow) along a data track (orange marks). Four data layers are seen, with the laser currently addressing the third from the top. The laser passes through the first two layers and only interacts with the third, since here the light is at a high intensity.
