2. 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 ...

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 ...

4. 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.

5. Nd:YAG laser - Wikipedia

   en.wikipedia.org/wiki/Nd:YAG_laser

   Nd:YAG laser with lid open showing frequency-doubled 532 nm green light. Nd:YAG laser rod. Nd:YAG ( neodymium-doped yttrium aluminum garnet; Nd:Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, neodymium in the +3 oxidation state, Nd (III), typically replaces a small fraction (1%) of the yttrium ions in ...

6. 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.
