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.
The YAL-1 with a low-power laser was test-fired in flight at an airborne target in 2007. [2] A high-energy laser was used to intercept a test target in January 2010, [3] and the following month, successfully destroyed two test missiles. [4] Funding for the program was cut in 2010 and the program was canceled in December 2011. [5]
The active laser medium (laser gain/amplification medium) is a gas discharge which is air- or water-cooled, depending on the power being applied. The filling gas within a sealed discharge tube consists of around 10–20% carbon dioxide (CO 2), around 10–20% nitrogen (N 2), a few percent hydrogen (H 2) and/or xenon (Xe), with the remainder ...
Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added [1] process involving the creation of machines, parts, and structures from various raw materials. Typically, a fabrication shop bids on a job, usually based on engineering drawings, and if awarded the contract, builds the product.
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 ...
Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, biodiesel, kerosene, etc) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to ...
