  2. Solid light - Wikipedia

    en.wikipedia.org/wiki/Solid_light

    Solid light, or hard light, is a hypothetical material consisting of light in a solidified state. It has been theorized that solid light could exist. [ 1 ] [ 2 ] Some experiments claim to have created solid photonic matter or molecules by inducing strong interaction between photons.

    An assortment of LED lamps commercially available as of 2010 as replacements for screw-in bulbs, including floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications. Solid-state lighting (SSL) is a type of lighting that uses semiconductor light-emitting diodes ...

    en.wikipedia.org/wiki/Gadolinium_oxysulfide

    The scintillator is the primary radiation sensor that emits light when struck by high energy photons. Gd 2 O 2 S based ceramics exhibit final densities of 99.7% to 99.99% of the theoretical density (7.32 g/cm 3 ) and an average grain size ranging from 5 micrometers to 50 micrometers in dependence with the fabrication procedure.

  6. Anthony McCall - Wikipedia

    en.wikipedia.org/wiki/Anthony_McCall

    Anthony McCall (born 1946) is a British-born New York based artist known for his ‘solid-light’ installations, a series that he began in 1973 with "Line Describing a Cone," in which a volumetric form composed of projected light slowly evolves in three-dimensional space.

  7. 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. [1] Semiconductor -based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called laser diodes .

  8. Line Describing a Cone - Wikipedia

    en.wikipedia.org/wiki/Line_Describing_a_Cone

    Line Describing a Cone is an avant-garde film produced in 1973 by artist Anthony McCall as part of his "solid light" film series. McCall's reduction of film to the essential properties of the medium resembles the work of other radical artists of his time, [1] and has inspired various projects by artists such as Stan Douglas, Richard Serra, and Gordon Matta-Clark.
