2. Laser metal deposition - Wikipedia

   en.wikipedia.org/wiki/Laser_Metal_Deposition

   Laser metal deposition (LMD) is an additive manufacturing process in which a feedstock material (typically a powder) is melted with a laser and then deposited onto a substrate. [1] A variety of pure metals and alloys can be used as the feedstock, as well as composite materials such as metal matrix composites .

3. Laser cutting - Wikipedia

   Diagram of a laser cutter Laser cutting process on a sheet of steel CAD (top) and stainless steel laser-cut part (bottom) 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 ...

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.

5. Selective laser sintering - Wikipedia

   en.wikipedia.org/wiki/Selective_laser_sintering

   An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.

6. List of laser applications - Wikipedia

   en.wikipedia.org/wiki/List_of_laser_applications

   Since a laser beam has low divergence, the laser light appears as a small spot even at long distances; the user places the spot on the desired target and the barrel of the gun is aligned (but not necessarily allowing for bullet drop, windage, distance between the direction of the beam and the axis of the barrel, and the target mobility while ...

7. Optical engineering - Wikipedia

   en.wikipedia.org/wiki/Optical_engineering

   Optical engineering is the field of engineering encompassing the physical phenomena and technologies associated with the generation, transmission, manipulation, detection, and utilization of light. [2] Optical engineers use the science of optics to solve problems and to design and build devices that make light do something useful. [3]
