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 ...
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).
The US-Israeli Tactical High Energy Laser (THEL) was used to shoot down rockets and artillery shells before being canceled in 2005 as a result of "its bulkiness, high costs and poor anticipated results on the battlefield". [1] A laser weapon [2] is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be ...
where t is the depth of cut, P is the laser beam power, v is the cutting velocity, and d is the laser beam spot diameter. [5] The depth of the cut is also influenced by the workpiece material. The material's reflectivity, density, specific heat, and melting point temperature all contribute to the lasers ability to cut the workpiece.
DragonFire is a British laser directed-energy weapon (LDEW). It was first unveiled to the public as a technology demonstrator in 2017 at the Defence and Security Equipment International (DSEI) conference in London and is being developed by UK DragonFire, a collaboration consisting of MBDA UK, Leonardo UK, QinetiQ and the Defence Science and Technology Laboratory (dstl).

The same conduction that works against the spot vaporisation of metal is an asset if the objective is to vaporise some other coating away from the metal. 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 ...

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 ...
