  2. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/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.

  3. Diode-pumped solid-state laser - Wikipedia

    en.wikipedia.org/wiki/Diode-pumped_solid-state_laser

    A diode-pumped solid-state laser ( DPSSL) is a solid-state laser made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, with a laser diode . DPSSLs have advantages in compactness and efficiency over other types, and high power DPSSLs have replaced ion lasers and flashlamp-pumped lasers in many scientific ...

  5. Vertical-cavity surface-emitting laser - Wikipedia

    en.wikipedia.org/wiki/Vertical-cavity_surface...

    The vertical-cavity surface-emitting laser ( VCSEL / ˈvɪksəl /) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also called in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer.

  6. Distributed-feedback laser - Wikipedia

    en.wikipedia.org/wiki/Distributed-feedback_laser

    Distributed-feedback laser. A distributed-feedback laser ( DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating. The structure builds a one-dimensional interference grating ( Bragg scattering ), and the grating provides ...

  7. Semiconductor laser theory - Wikipedia

    en.wikipedia.org/wiki/Semiconductor_laser_theory

    Semiconductor lasers (660nm, 532nm, 405nm) Semiconductor lasers or laser diodes play an important part in our everyday lives by providing cheap and compact-size lasers. They consist of complex multi-layer structures requiring nanometer scale accuracy and an elaborate design. Their theoretical description is important not only from a fundamental ...

  8. List of laser applications - Wikipedia

    en.wikipedia.org/wiki/List_of_laser_applications

    Most laser sights use a red laser diode. Others use an infrared diode to produce a dot invisible to the naked human eye but detectable with night vision devices. The firearms adaptive target acquisition module LLM01 laser light module combines visible and infrared laser diodes.
