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 ...
Theodore Harold Maiman (July 11, 1927 – May 5, 2007) was an American engineer and physicist who is widely credited with the invention of the laser. [1] [2] [3] [4 ...
Schawlow and Townes had already applied for a patent on the laser, in July 1958. Their patent was granted on March 22, 1960. Gould and TRG launched a legal challenge based on his 1957 notebook as evidence that Gould had invented the laser prior to Schawlow and Townes's patent application.
Lasers are used in fiber-optic and free-space optical communications, optical disc drives, laser printers, barcode scanners, semiconductor chip manufacturing (photolithography, etching), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and ...
E - Laser beam. F - Pumping cavity. G - Ruby rod. H - Trigger wire. A ruby laser is a solid-state laser that uses a synthetic ruby crystal as its gain medium. The first working laser was a ruby laser made by Theodore H. "Ted" Maiman at Hughes Research Laboratories on May 16, 1960. [1] [2]
The laser printer was invented at Xerox PARC in the 1970s. Laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.
Gary Keith Starkweather (January 9, 1938 – December 26, 2019) [1] was an American engineer who invented the laser printer and color management.. Starkweather received a B.S. in physics from Michigan State University in 1960 and an M.S. in optics from the University of Rochester in 1966.
Chandra Kumar Naranbhai Patel (born 2 July 1938) is an electrical engineer.He developed the carbon dioxide laser in 1963; [1] it is now widely used in industry for cutting and engraving a wide range of materials like plastic and wood.
