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 ...
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 ...
The first laser, invented by Theodore Maiman in May 1960. Nd:YAG laser: 1.064 μm, (1.32 μm) Flashlamp, laser diode: Material processing, rangefinding, laser target designation, surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam). One of the most common high ...
When the laser was first invented, ... Typical sealed CO 2 lasers used in industrial laser cutting: Examples of pulsed systems with high peak power: 700 TW ...
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.
In 1961, R.W. Hellwarth invented a method of q-switching, to concentrate the output into a single pulse. [15] Ruby laser pistol constructed by Stanford Univ. physics professor in 1964 to demonstrate the laser to his classes. The plastic body recycled from a toy raygun contained a ruby rod between two flashtubes (right).
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.
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.
