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. Laser diode - Wikipedia

A laser diode ( LD, also injection ...

4. 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.

5. Transparent ceramics - Wikipedia

   en.wikipedia.org/wiki/Transparent_ceramics

   Transparent spinel (MgAl 2 O 4) ceramic is used traditionally for applications such as high-energy laser windows because of its excellent transmission in visible wavelengths and mid-wavelength infrared (0.2–5.0 μm) when combined with selected materials – source: U.S. Naval Research Laboratory [citation needed] Many ceramic materials, both ...

6. 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 ...

7. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   Poly ( methyl methacrylate) ( PMMA) is the synthetic polymer derived from methyl methacrylate. It is used as an engineering plastic, and it is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others ( see ...
