  2. Plasma cutting - Wikipedia

    en.wikipedia.org/wiki/Plasma_cutting

    Plasma cutting. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops ...

  3. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    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.

  4. Plasma acceleration - Wikipedia

    en.wikipedia.org/wiki/Plasma_acceleration

    plasma wakefield acceleration (PWFA): The electron plasma wave is formed by an electron or proton bunch. laser wakefield acceleration (LWFA): A laser pulse is introduced to form an electron plasma wave. laser beat-wave acceleration (LBWA): The electron plasma wave arises based on different frequency generation of two laser pulses. The ...

  5. 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. At high laser flux, the material is typically converted ...

  6. Pulsed laser deposition - Wikipedia

    en.wikipedia.org/wiki/Pulsed_laser_deposition

    Pulsed laser deposition (PLD) is a physical vapor deposition (PVD) technique where a high-power pulsed laser beam is focused inside a vacuum chamber to strike a target of the material that is to be deposited. This material is vaporized from the target (in a plasma plume) which deposits it as a thin film on a substrate (such as a silicon wafer ...

  7. Free-electron laser - Wikipedia

    en.wikipedia.org/wiki/Free-electron_laser

    Free-electron laser. The free-electron laser FELIX Radboud University, Netherlands. A free-electron laser (FEL) is a fourth generation light source producing extremely brilliant and short pulses of radiation. An FEL functions much as a laser but employs relativistic electrons as a gain medium instead of using stimulated emission from atomic or ...

  8. Plasma torch - Wikipedia

    en.wikipedia.org/wiki/Plasma_torch

    Plasma torch. A plasma torch cutter. A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [1][2][3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [4]

  9. Laser engraving - Wikipedia

    en.wikipedia.org/wiki/Laser_engraving

    Laser marked electronic part. Laser engraving is the practice of using lasers to engrave an object. The engraving process renders a design by physically cutting into the object to remove material. The technique does not involve the use of inks or tool bits that contact the engraving surface and wear out, giving it an advantage over alternative ...
