2. Laser engraving - Wikipedia

   en.wikipedia.org/wiki/Laser_engraving

   Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.

   Trotec laser system. Trotec manufactures both flatbed and galvo laser systems, as well as bespoke solutions for specialist clients. Its CO 2 lasers range from 12 to 500 watts and its fiber laser systems range from 10 to 50 watts. [3] In 2008 Trotec introduced the Rayjet, a desktop laser system aimed specifically at small and medium enterprises. [4]

4. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   4000 watt CO 2 laser cutter. There are three main types of lasers used in laser cutting. The CO 2 laser is suited for cutting, boring, and engraving. The neodymium (Nd) and neodymium yttrium-aluminium-garnet lasers are identical in style and differ only in the application. Nd is used for boring and where high energy but low repetition are required.

5. List of laser types - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_types

   Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).

6. Nd:YAG laser - Wikipedia

   en.wikipedia.org/wiki/Nd:YAG_laser

   The Nd:YAG laser is the most common laser used in laser designators and laser rangefinders. During the Iran–Iraq War, Iranian soldiers suffered more than 4000 cases of laser eye injury, caused by a variety of Iraqi sources including tank rangefinders. The 1064 nm wavelength of Nd:YAG is thought to be particularly dangerous, as it is invisible ...
