  2. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, [1] leaving an edge with a high-quality surface finish. [2]

  3. Laser ablation - Wikipedia

    en.wikipedia.org/wiki/Laser_ablation

    Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .

    A Gaussian beam photographic paper burn comparison of a carbon dioxide transversely-excited atmospheric-pressure laser obtained during the optimization process by adjusting the alignment mirrors. The optical resonator , or optical cavity , in its simplest form is two parallel mirrors placed around the gain medium, which provide feedback of the ...

  6. Ion laser - Wikipedia

    en.wikipedia.org/wiki/Ion_laser

    A krypton laser is an ion laser using ions of the noble gas krypton as its gain medium.The laser pumping is done by an electrical discharge.Krypton lasers are widely used in scientific research, and in commercial uses, when the krypton is mixed with argon, it creates a "white-light" lasers, useful for laser light shows.

  8. Excimer laser - Wikipedia

    en.wikipedia.org/wiki/Excimer_laser

    An excimer laser, sometimes more correctly called an exciplex laser, is a form of ultraviolet laser which is commonly used in the production of microelectronic devices, semiconductor based integrated circuits or "chips", eye surgery, and micromachining.

  9. Helium–neon laser - Wikipedia

    en.wikipedia.org/wiki/Helium–neon_laser

    Helium–neon laser at the University of Chemnitz, Germany. A helium–neon laser or He–Ne laser is a type of gas laser whose high energetic gain medium consists of a mixture of helium and neon (ratio between 5:1 and 20:1) at a total pressure of approximately 1 Torr (133 Pa) inside a small electrical discharge.
