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. Carbon-dioxide laser - Wikipedia

   en.wikipedia.org/wiki/Carbon-dioxide_laser

   The carbon-dioxide laser ( CO2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [ 1] and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available. They are also quite efficient: the ratio of output ...

   The laser diode chip is the small black chip at the front; a photodiode at the back is used to control output power. SEM ( scanning electron microscope) image of a commercial laser diode with its case and window cut away. The anode connection on the right has been accidentally broken by the case cut process. A laser diode ( LD, also injection ...

5. 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 ...

6. List of laser types - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_types

   Laser diode Fiber version is capable of producing several-kilowatt continuous power, having ~70-80% optical-to-optical and ~25% electrical-to-optical efficiency. Material processing: cutting, welding, marking; nonlinear fiber optics: broadband fiber-nonlinearity based sources, pump for fiber Raman lasers ; distributed Raman amplification pump ...

7. List of laser applications - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_applications

   Diode lasers are used as a lightswitch in industry, with a laser beam and a receiver which will switch on or off when the beam is interrupted, and because a laser can keep the light intensity over larger distances than a normal light, and is more precise than a normal light it can be used for product detection in automated production.
