2. Laser cutting - Wikipedia

   en.wikipedia.org/wiki/Laser_cutting

   For sheet metal cutting, the focal length is usually 1.5–3 inches (38–76 mm). [7] [8] Advantages of laser cutting over mechanical cutting include easier work holding and reduced contamination of workpiece (since there is no cutting edge which can become contaminated by the material or contaminate the material). Precision may be better since ...

3. 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).

4. 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.

6. Sheet metal - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal

   The metal is heated and burnt by the laser beam, cutting the metal sheet. [20] The quality of the edge can be mirror smooth and a precision of around 0.1 mm (0.0039 in) can be obtained. Cutting speeds on thin 1.2 mm (0.047 in) sheet can be as high as 25 m (82 ft) per minute.

7. Marquetry - Wikipedia

   en.wikipedia.org/wiki/Marquetry

   Cutting-edge tech has also been applied to marquetry. Among these is laser cutting, where the design is drawn or imported as a CAD or vector file and each piece is cut separately; each different species of wood-and thickness-may need a specific adjustment of the beam power; the offset will determine the gap between the pieces. In some cases ...
