  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. Selective laser melting - Wikipedia

    en.wikipedia.org/wiki/Selective_laser_melting

    Selective laser melting (SLM) machines can operate with a work space up to 1 m (39.37 in) in X, Y and Z. Some of the materials being used in this process can include Ni based super alloys, copper, aluminum, stainless steel, tool steel, cobalt chrome, titanium and tungsten.

    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.

  6. 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.

  7. Selective laser sintering - Wikipedia

    en.wikipedia.org/wiki/Selective_laser_sintering

    Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.

  8. X-ray crystallography - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystallography

    X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions. By measuring the angles and intensities of the X-ray diffraction, a crystallographer can produce a three-dimensional picture of ...

    The Ti:sapphire crystal is the bright red light source on the left. The green light is from the pump diode Titanium-sapphire lasers (also known as Ti:sapphire lasers , Ti:Al 2 O 3 lasers or Ti:sapphs ) are tunable lasers which emit red and near-infrared light in the range from 650 to 1100 nanometers.

  11. 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.
