  2. Bubblegram - Wikipedia

    en.wikipedia.org/wiki/Bubblegram

    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.

  3. Laser engraving - Wikipedia

    en.wikipedia.org/wiki/Laser_engraving

    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.

  4. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics.

  5. 5D optical data storage - Wikipedia

    en.wikipedia.org/wiki/5D_optical_data_storage

    5D optical data storage (also branded as Superman memory crystal, 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.

  7. Liquid-crystal laser - Wikipedia

    en.wikipedia.org/wiki/Liquid-crystal_laser

    Liquid-crystal laser. A liquid-crystal laser is a laser that uses a liquid crystal as the resonator cavity, allowing selection of emission wavelength and polarization from the active laser medium. The lasing medium is usually a dye doped into the liquid crystal.

  8. Laser crystal - Wikipedia

    en.wikipedia.org/wiki/Laser_crystal

    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, typically a plastic block. Category: Disambiguation pages.

  9. Solid-state laser - Wikipedia

    en.wikipedia.org/wiki/Solid-state_laser

    A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. Semiconductor -based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called laser diodes .

  10. 3D scanning - Wikipedia

    en.wikipedia.org/wiki/3D_scanning

    3D laser scanning is used by the law enforcement agencies around the world. 3D models are used for on-site documentation of: Crime scenes; Bullet trajectories; Bloodstain pattern analysis; Accident reconstruction; Bombings; Plane crashes, and more; Reverse engineering

  11. 3D microfabrication - Wikipedia

    en.wikipedia.org/wiki/3D_Microfabrication

    Three-dimensional (3D) microfabrication refers to manufacturing techniques that involve the layering of materials to produce a three-dimensional structure at a microscopic scale. [1] These structures are usually on the scale of micrometers and are popular in microelectronics and microelectromechanical systems .
