Laser was originally an acronym for "Light Amplification by Stimulated Emission of Radiation". It uses a quantum mechanical effect, stimulated emission, to generate a very collimated, monochromatic and coherent beam of light.
Common light sources, such as the electric light bulb emit photons in all directions, usually over a wide spectrum of wavelengths. The light is also incoherent, i.e., there is no fixed phase relationship between the photons emitted by the light source. By contrast, a laser emits photons in a narrow, well-defined beam of light. The light is often near-monochromatic, consisting of a single wavelength or color, and is highly coherent, and is often polarised.
Holography (from the Greek, holos whole + graphe writing) is the science of producing holograms, an advanced form of photography that allows an image to be recorded in three dimensions.
Holography was invented in 1947 by Hungarian physicist Dennis Gabor (1900-1979), for which he received the Nobel Prize in physics in 1971. The discovery was a chance result of research into improving electron microscopes at the British Thomson-Houston Company, and the field did not really advance until the invention of the laser in 1960.

Holograms (photons) and than holatoms (atoms)
Holograms are created with photon lasers beaming a ‘quantity’ or ‘wave’ of focused light. I believe we could create a material object, a holatom with an atom laser. This will stretch our technology too the limits…. And beyond.
