  2. Theodore Maiman - Wikipedia

    en.wikipedia.org/wiki/Theodore_Maiman

    Theodore Harold Maiman (July 11, 1927 – May 5, 2007) was an American engineer and physicist who is widely credited with the invention of the laser. [1] [2] [3] [4 ...

  3. Laser - Wikipedia

    en.wikipedia.org/wiki/Laser

    A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser originated as an acronym for light amplification by stimulated emission of radiation.

  4. LeGrand Van Uitert - Wikipedia

    en.wikipedia.org/wiki/LeGrand_Van_Uitert

    LeGrand Van Uitert (May 8, 1922 in Salt Lake City – June 3, 1999 in Morristown, New Jersey) was an American scientist who co-invented the first continuous beam optical MASER, now known as a laser, using a synthetic rare-earth doped garnet crystal. [1]

  5. Gordon Gould - Wikipedia

    en.wikipedia.org/wiki/Gordon_Gould

    For example, the first operating laser, a ruby laser, was optically pumped; the helium–neon laser is pumped by gas discharge. The delay—and the subsequent spread of lasers into many areas of technology—meant that the patents were much more valuable than if Gould had won initially.

  6. Ruby laser - Wikipedia

    en.wikipedia.org/wiki/Ruby_laser

    A ruby laser most often consists of a ruby rod that must be pumped with very high energy, usually from a flashtube, to achieve a population inversion.The rod is often placed between two mirrors, forming an optical cavity, which oscillate the light produced by the ruby's fluorescence, causing stimulated emission.

  7. Laser science - Wikipedia

    en.wikipedia.org/wiki/Laser_science

    Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. [ 1 ] Laser science is principally concerned with quantum electronics , laser construction , optical cavity design, the physics of producing a population inversion in laser media , and the temporal evolution of the light field in the laser.

    Charles Hard Townes (July 28, 1915 – January 27, 2015) was an American physicist. [4] [5] Townes worked on the theory and application of the maser, for which he obtained the fundamental patent, and other work in quantum electronics associated with both maser and laser devices.
